No no I didnt word that sentence very well. Team A is fine on mana, Team B would get killed by not having replenishment (no mana totem or blessing of wisdom).

The whole purpose of the swap is to get tremor totem + resist totems to my Team B. They get completely blasted by fear spamming mobs (I can sometimes wipe in DTK because of being feared into another group or healer getting feared, etc) Plus I have only 75 resist to ALL and 120 Shadow resist. As a group that's no good when you go up against massive magic damage bosses.

So to recap: I need to get one shaman to team B for the tremor totem. All the rest is gravy.
