I'm not saying it will negatively impact the game. What I'm saying is it does not positively impact it either, because cookie cutter builds will be the result. You either go cookie cutter, or be suboptimal.

Edit: If you don't know what "cookie cutter" means, go google it. It means to follow a standard formula that lacks originality, just like how a cookie cutter always cuts cookies in the same shape. When applied to RPGs (particularly MMORPGs), it means to build your character in a certain way to min-max your stats, and the ways to do this is very limited. To deviate from it means to do less damage than everyone else.
