in wow there is dps charts and it makes the game feel more like a job and trying as hard as you can to just get good dps instead of playing for fun and using different strategy's

maybe a blizzard employee can confirm that there is no dps charts

(i have wow and my dps is good but thats not the problem i just want to lay back)

There are no DPS charts in World of Warcraft.

People have though created add-ons which attempt to compare the DPS of each player, as well as healing output, absorption, etc. These aren't included in the game, nor are they supported. Personally I think they can be useful to a point, but are abused by people who don't know how to use and read them properly, and are too commonly relied on as a means to judge the performance of others.

In any case, Diablo III doesn't provide customizable UI through add-ons, and we have no intent to provide DPS charts.
