So stop avoiding it and let it hit you so he can take the spell, thus stun the boss on epicenters. Overall this means more healer mana is saved; sure, the tank is taking more damage, but the raid is taking far less (if any at all).
Also you should be able to do tank swaps no problem, even if lightning fists hasn't been cast. Just stand behind the warrior so he can steal the spell: if he stands close enough to the boss he won't actually get hit by it: it seems to start a short distance away from the boss. So if you're right underneath him you'll be fine, but if you stand at the very edge of his hitbox you'll get hit.
That was my experience of it anyway.
