Avoid aoin like the PLAGUE!
It's a truly abysmal game.
If it's not timesinks, it's either money or resource sinks.
The game balance for want of a better word is retarded, you can basically rule out melee classes in PVP.
Not only is there an XP grind for levels, then you have to grind PVP levels, and the more points you have, the more you lose when you get killed.
Also prepare to be ganked a LOT.
Once you hit about 20-25, the levels you grind in are open to the other side, so packs of 50's come along and slaughter the lowbies, because there is nothing else to do whatsoever once you hit the upper levels.
You have to pay for everything!, when you die, you pay.
When you get to a new area you have to bind there, for which you pay, the higher level you are, the more you pay.
There are no mounts, so you spend a HUGE amount of time travelling.
Craft skills are pants, the resources needed are prohibitively expensive, or take an inordinate amount of time to gather, many require rare items, which are truly rare in the sense that they are hard to acquire, but are a staple of making items.
Oh and the number of quests which have you travelling halfway round the world of which there are many, simply to finish by talking to some dude 20 feet away from the dude who gives you the quest will drive you insane!!!!!!!!!!!!!
It's so unbalanced,that every 2 weeks they had a double xp weekend simply to allow people to level up!
Cheating and gold sellers are rampant and ignored by the devs.
There is no support, the forums are pants.
Then there is the pathetic attempt to make it a pay to play game, for example on Valentines weekend, you could pay 7 Euro, half a months subscription for some fucking chocolates and 10 red dyes!(and that was per TOON NOT PER ACCOUNT).That's where their priorities lie, fluff and ephemera, stuff that actually makes no impact on the game, but looks "pretty".
