How people can play pandaren warriors. They look bad in plate armor (Especially male ones, ) IMO.
Blood Elf for life. Collision, Dark and Jalopy are all newbs for thinking otherwise
All in all OP their is no big book of "You have to be and orce to do max dps". Its your decision pick what you want the most.
You don't *HAVE* to do anything to improve DPS in this game. But if someone is asking how to improve DPS we're going to tell them how to improve DPS.
Just because you are content with not mix/maxing doesn't mean others are not. And while race can be subjective, if you care about looks or animations, the best choice is clearly OBJECTIVE.
So you can disagree on SUBJECTIVE grounds, how one looks v another, flavor things, etc, but the OBJECTIVE choice is clear. And that is what OP wanted.
Professions have a higher effect on your DPS than Racials. The moment racials actually make or break PvE encounters constantly is the moment Blizzard whips up a hotfix nerf that would make the Human/Undead PvP nerfs look like cosmetic changes.
Just pick something that appeals to you cosmetically. Its the last major content patch of the Expansion, and Racial balance is a priority matter on Blizzard "to do" list for the next expansion, so what you see now is going to change.
