Driving with a healer is fun, but add in a little lag and some WOW weirdness and it doesnt work out too well. Sometimes when I tell my guys to attack something they will run THROUGH the target and about 30 yards before turning around and heading back. This is lost dps time and in pvp someone will most likely have died (or lived). It's not something that happens everytime, but its enough to annoy and make me wonder why I run a melee group.
