I used to hate the vehicles now, and certainly don't enjoy them in a raiding atmosphere, but I'm now liking their use in PvP. As long as Blizzard keeps it so less than 25% of the players in a BG actually use the vehicles, and the rest of the players continue healing/DPSing like normal, then I welcome the change. It certainly sucks to have your team plowed by a vehicle, but there's also satisfaction when your team alone takes one out.
