I haven't done anything but AB on my shaman team, but I'm 9 wins, 0 losses there... every time I've had close to losses I've been able to convince people to quit being awed by me and actually go play... the worst one I had 3 followers, putting us @ 7 players at the node I was at... I'd move, they'd follow, they would sometimes kill who i fought, but most often people died fast enough without them...

I've got a 5th shaman now and I've vowed not to play again til 70, but all said and done, I don't see the 5 boxer as the weak point. Especially in AB if they will work with you that leaves 2 for each node of a 5 cap, and you to roll defense between the nodes as a mobile gank squad...
