All those nerf do are reducing fun in game. I don't play RPGs to be "competetive". I paly them to have fun.
For a lot of people, the two are synonymous. Though for me, video games have been a haven from what I regard as the menace of competitive team sports, so although I can't really object to them being catered to at all, I would object to finding myself having the choice between joining in or leaving.
