I dunno about breaking follow being a pain. I have a main macro "/assist <maintoon>, /follow <maintoon>" and I tap it about 2-3 times before each target to make sure they all have the same target and are on my caboose.

Now, I put that macro in keyslot 1, and lightning in keyslot 2....so each time my tank picks a target:
1,1,2 and boom, I'm attacking. It's not too bad to constantly ensure each is in follow.
