So, this some is kind of troll thread? Cause either this or it's based on total ignorance of the game.
There are a number of quests where strategy and skill at other things than dos are a lot more important than dps.

Not to mention dps alone isn't really worth that much in this game where enemy damage is super high and it's always a pain to see that glass cannon with his fancy gear die all the time and in the end not contribute very much cause dead dps is zero dps.

It's mentalities like that that caused me to stop playing CQ and TD 3 / 4 because so called pro players with their high dps failed hard at all content that wasn't based on purely getting the highest paper dps.
