Man, it's always something every expansion.
When they changed the loot system for LFR in Cata, I wondered why they didn't make the loot system like that across the Board? From LFR to Mythic, you either get personal loot that's BOP or you get a sack of gold. Same for mounts. No need to link who got what in chat. Ninja loot issue solved. Asshole reserved loot issue, solved. It's not going to affect raiding. People will raid for the level for the level of gear they want. If anything it will make more control freaks leave the game, which would result in a Better wow community, what's left of it anyway.
