Take your favorite class and completely over power it

[Heart of Darkness]

Medic from TF2:

Übercharges can be deployed whenever and never run out.
Passive healing is bumped up to 50 HP per second.
The Syringe Gun has triple the fire speed, heightened accuracy, and now has three times the power.
The Bonesaw has a 100% chance to crit and has a base damage of 180.
His speed is now 150% of average speed.

 

[zenoaugustus]

Druids (WoW): Make aquatic form useful. All shall fear the sea lion.

 

[Master Kuja]

Medic from BfBc 2 with 10 times as much health.

Recon from BFBC2.
Every shot from the VSS is a one shot kill and every round penetrates MBT armour.

Riposte!

---

Engineer from BFBC2.
Carl Gus-
Oh wait.

 

[atled3]

Outlaw on inFAMOUS.

I'll give Cole a Lightsaber, a machine gun, and wolverine's healing abilities.

Cole's powers prevent him from holding a gun. As for healing abilities if he had a packback of batteries, that would take care of it. also he doesn't need a lightsaber as he has an electricity blade power. Now what cole really needs is a wet suit (and that waterproof backpack of batteries).

Well, give him something that doesnt involve an explosive charge and he's golden.

Just give him the Volt-driver from Metro 2033 it's ludicrously powerful, it's only weakness is that it has to be charged so Cole could make very good use of it.

Spy- Infinite cloak time, backstabbing doesnt cause you to uncloak. Immune to being set on fire while cloaked.

Ah why not, frontstabs are also instakills.

I'd really like sappers to give turrets a 5 second cooldown in which it cannot fire when they are removed with a wrench.

 

[Mr.Squishy]

Sniper/ Assassin -

You can become invisible, which has no limit. No one can detect you and you can shoot and stab while invisible without turning visible.

Overpowered much?

Oblivion. Four not-too-hard steps.
1. become arch-mage (or otherwise be granted access to enchanting; I haven't played in a while, so I'm kind of rusty.)
2. enchant all your armor with 20% chameleon(the invisibility won't disappear even if you attack). make sure to get boots, greaves, headgear, shields, what have you.
3. ???
4. PROFIT

OT: D&D 3.5 Edition, here I come.

Mages. Allow them to wear armor and use their INT to get AC bonuses. And grant them the use of metamagic feats without having to use higher-leveled spell slots to use them. Also, D&D style, some manner of mana potion to restore spells that has been used already that day.

Or just play a druid. 8th spell level (17th char.level or so out of 20 - well, you can advance further even after that, but let's not go into that.) that lets you FLY AND SHOOT LIGHTNING FROM YOUR EYES. Also, Animal companion and wild shape, as well as Regenerate.

Or Clerics. Harm does 100 HP of damage direct, just like that. And it's fairly low-leveled. And youget a Mass version of it, I think. Same for Heal, only with, well, healing. And spontaneous healing (or harming) spells in place of other prepared spells. Losing 'read magic' for cure light wounds is a very acceptable sacrifice. Also, go into a necromancer's lair and turn undead. At the right level, you will be a god. Bonus points for sun and/or trickery domain (which lets you get time stop at 9th spell level).

Or Fighter. You get more than double the feats any other class does (mostly fighting-related ones, but if you use those right as well as skill points, gods help your enemies).

Or monks. They self-heal. They teleport. They attack 4 times in one round before reachcing level 10. They can speak to every living thing ever. They don't age. They can defy gravity to a degree. They're extra fast. They get AC bonuses. And Pelor help you if they find the Book of Exalted Deeds and take the Vow feats (it's like giving them space marine armor and a chainsword). They get spell resistance. They get poison/disease immunity.

So yeah...

 

[SturmDolch]

Black Ops: My SPAS-12 now shoots incendiary rounds, like in the campaign.

 

[Omikron009]

The spitter from left 4 dead 2, who spits acid and boomer bile at the same time.

 

[mitchell271]

ghosts from starcraft 2
infinite nukes that have a x100 damage modifier, it takes one millisecond to target them

 

[Treblaine]

TF2. Engineer's turret can now fire over an extremely long distance at twice the normal fire-rate and has a shield to absorb any damage plus a fellow engineer can still repair sentry.

yeah, valve would be crazy to do something like that... oh wait...

 

[Onyx Oblivion]

100% Chameleon.

You need fuck-all else.

 

[Fenra]

TF2 engineer, can build as many turrets as they have metal for, dispensers now restore 200 metal per tick at level one

 

[USSR]

I think the Battlefield medic's defib unit should be able to shoot lightning. It would be so much more interesting

I spilled my Pepsi at the thought of that.

 

[RUINER ACTUAL]

When I make a class in CoD4 or MW2, I over power it to myself. I can shoot people at mid and long range just fine, but I like to operate CQC a lot because a lot of people have trouble with it. They can't track targets or react fast enough close up. I use a Vector with an M1014 in MW2 with FMJ and Stopping Power. It works great and I get bitched at. Also, I don't knife.

 

[Fuselage]

TF2 Scout:
He can run at 100% speed and have a slow motion ability, And has a special ability after dominating 10 people, He can noclip through walls!!!!

 

[Tharwen]

I think the Battlefield medic's defib unit should be able to shoot lightning. It would be so much more interesting

I spilled my Pepsi at the thought of that.

Gwahahaha! My plan worked! Your keyboard is now possibly slightly sticky, much to my delight.

Anyway, yeah. Lightning. It would probably be more realistic than the way they currently work...

 

[VulakAerr]

My Loremaster in LOTRO with a cadre of healing spells (Other than the personal heals). Not only can I debuff the shit out of everything, but I can heal through their pathetic damage.


Also, C4 in BC2 now has a 50 yard throw range. No more mumbling to yourself as you run up to that Abrams: "Please don't turn around, pleeeeease don't turn around... OH GOD HE SEES ME"

Carl Gustav is reverted back to pre-nerf power.
Annnd...the SV98 is now silenced and leaves no vapor trail.

My Loremaster in LotRO has an AE mez.

My Engineer in BC2 can hit the gas tank of any light vehicle and then light the trail of fuel on fire.

 

[XzarTheMad]

TF2 Soldier: Immune to Headshots, Immune to Backstabs, Takes no damage from Rocket Jumps, Buff Banner grants full crits when deployed, Buff Banner has +200% buff time, +100% ammo count

It's OP without making it not-fun. Just removes his biggest liabilities and boosts his overall badassitude.

TL;DR: Play on a saigns server.
No, seriously. On those servers, "premium" members get the following:
Much faster run speed
Ammo regeneration
+30 HP on kill
No reload (ammo regens in active clip)
Quadrouple jump for scout
Double firing speed

Only good thing about those servers is that it's always terrible players playing there, so stomping their ass, even if they're premium, is pretty easy.

 

[Fishyash]

WoW hunters. Aimed shot is insant cast and 1 hits everyone with unlimited max range and no min range. Coasts 0 focus, no cooldown

Oh and beastial wrath should make hunters and their pets invincible. Of course. Unlimited duration. Lasts until cancelled. Gives you aimed shot. Makes all abilities cost 0 focus.
