This is of course nonsense. As long as there are significant traits you will never be competitive by just putting in points wherever you feel like putting them in. People who play by using whichever skills they find the coolest instead of tuning their builds for optimal combos will be slaughtered in competitive play.
It will be just like any other game, the hardcore people will figure out the optimal builds and skill combos to use, write up cookie cutter build guides and most people will follow. Those who don't will be stuck doing the easy mode RP content.
