Only if the building did not work like any other game, since as people said the best build is found with maybe one ability you change between one raid boss and the next to deal with one mechanic easier. (which will be given in guides and most people will play that build). Not sure how to make build matter without basically having one job with one set of skills like we have now. (which yes the different jobs are different builds ie healer heals, but sch does fairy/ shields, whm... etc.). So you would have to make builds vastly different but viable, and we are already seeing some not taking X in PFs (which should not exist.. but it does).
