This gets really old really fast because it's not exactly creative. The chains just make it so you can hit the same key several times in a row instead of have to hit several buttons in a sequence. You can't combine attacks to create your own unique combos or anything remotely interesting like that.

Also, after level 25 the game turns into a giant gankfest and you almost completely run out of quests to do, so you are required to run the same dungeon every day for XP, and that dungeon has a 17 hour reset timer, so ... yeah, Aion sucks.
