Most people say that, but people like me (those people playing since alpha) have spent SO MUCH TIME mastering this, and we're not ready for a possible new generation of people to be better than the grandpas of the game. Also this effects the YouTubers like huahwi, a expert PvPer, and now he'll just be mediocre.
First things first, I have a lot of respect for "minecraft veterans". With that out of the way, I think this change can benefit a lot of the PvP community. Change is inevitable, we just have to get used to. Its like every other update, only this time its PvP, not map making or redstone or building.
