Just wanted to get some others' insights on some hidden gems as far as talents and abilities go, as it pertains to multiboxing. Certain things that help create synergy, passive/easily activated abilities, etc.

For one, I chose the talent Brambles in my Balance Druid tree. Not only does it add to my tank's agro a little bit, but there's really no other Tier 2 Balance talents worth getting, IMO. Also, using Magma Totem with my Shaman has worked out pretty well in AOE situations, since the damage from Consecration takes agro away from it.
