#1 toxic community
Blizzard removed every single elite quest from the game and then increased exp for normal quests removing any need for group interaction
Seems like everything they change moves it away from a MMO and closer to a FPS. There is ZERO reason to ever group while leveling. Because of LFR there really isnt even any need to join a raiding guild. They can fix all of this by pulling the MMO back into MMORPG. Make community matter. Make it so terrible rude ninja looting asshole who AFK during LFR arent rewarded. Make it so you need to group up while leveling to finish certain quests. Epics should be EPIC and require raids to get. Not simply hitting up LFD for some wellfare gear.
