If it's not fun then stop.. nothing wrong with that. It's only a game.

IMO I don't believe Bliz has intentionally done anything to break boxers playstyle. Just part of the evolution of the game. I can see /follow being made to work in the future for vehicles. I think some of the frustrations that people might have comes from the all shamie teams. In BC most of the time a full shaman group would outdps the content. Right now the new dungeons are designed with 4dps slots in mind (tanks now contribute to the dps). In BC the design was with 3dps.. so it was easy for a 5 shaman team just wreck the place.

I'm personally taking it easy, I'm leveling 4 teams.. switching between them depending on what I feel like playing. They're mostly at 71/72 right now and I don't really feel like rushing through the content.

WIth the whole phasing .. I didn't really have problems so far. I rolled 4 DKs and at the start quests never had a problem with some being left behind.
