Riot already tried the range nerf on Diana's ult, and it was reguardedly by pretty much everyone to be a mistake because it damages her kit cohesion in a big way, so it got reverted. I really don't see any reason for that aside from personal bias considering Diana is hardly a problematic champion in her current state.
