*sigh*
You know, judging by the insult at the top of your post, I assume your a moron assuming that all the hate towards the dumbing down of Bioware is being hurled by PC gamers.
I'd like to say I'm a pure console gamer, and I'm also pissed off.
Now, to briefly go over the basics of why Mass Effect to was dumbed down:
A fair few things were cut.
Mass Effect 1 skills:
Mass Effect 2 skills:
You mentioned that you never used all your skills at once.
I'll have to correct you and add that,
yes you could.
Combining Biotic powers was great fun.
Lifting enemies into the air and then using a force push to send em flying.
Using singularity to draw them together and blasting a Shotgun rocket into the mass.
Or just lifting an entire room into the air with various Biotics, activating all your damage buffs and start blowing them all apart.
The new way the karma bars worked encouraged extremism in either Paragon or Renegade.
In the old game you had to focus your skill points into diplomacy, which allowed you to play a morally grey Shepard and still be effective.
In Mass Effect 2 you had to be either a Saint or Devil in order to be good at diplomacy.
The inventory was gone. Say it was crap all you like, I'd agree with you.
But Bioware just got rid of it, instead of making it more user friendly. That was not streamlined, that was tearing out a whole part of the RPG experience.
This also lead to the utter idiocy of having the female characters surviving the vacuum of space with nothing but a breather mask.
After all, players will get bored if the tits are covered up right brah?
Oh, and the weapon mods were gone because of this as well.
Which meant rather then having my own gun which suited my play style, I was forced to use standard issue cookie cutter ones. Again, less freedom, less variety, less RPG.
Combat was more focused on cover based shooting. It was much smoother, and I liked it...
But it lost the variety of the first game. That one had enemies that could crawl on the ceiling and snipe, the Krogan were lighting fast melee chargers, more large enemies like Geth Colossus, the environments were not all corridors but instead there were many open spaces and the Geth were just generally more interesting then the Blue Suns/Blood pack.
All the enemies in Mass Effect 2 operated the same.
There was a lack of quest variety. Almost all quests involved mass amounts of shooting corridors and killing. Not as bad as Dragon Age 2, but still more then Mass Effect 1.
The first game had quiet a few quests where you didn't shoot anyone at all and instead had to use your wits and silver tongue.
The Mako was cut in favor of Planet Scanning. Again, lack of gameplay variety. Sense of grandure and exploration lost, even if the Mako did handle like a toaster on wheels.
And planet scanning was boring.
They could have focused on improving the Mako, rather then just scraping it.
The main plot really didn't hold up under scrutiny. Go read Shamus Young's article for a full break down. It's a entertaining and interesting read.

The collecters and Harbinger were failures and generated no threat.
Compared to Saren, a worthy rival, and Sovereign, famous for the chilling speech about the Reapers motivations. Which leads to...
The awful and silly tacked on final boss. Which also ruined the whole enigma the Reapers had built up. Worst of all, people were laughing, rather then chilled.
Those are some abridged notes on how it was dumbed down.
On the whole, Mass Effect 2 streamlined rather well. Better then Dragon Age 2 and some other titles. Much better actually, presentation and the shooting mechanics were slick.
But it lost alot of the other things that made it great, unique and epic in scope.
