Strategies for tank getting MC?

[Fused]

You will have to give examples of instances and mobs and your group composition. ZG was my first painful encounter, not MC but that froggy hex really screwed me up.

Mobs (List will increase as i lvl)
Slave Pen: Soothsayer & another caster class (dont recall name off hand).
Sethekk halls: Time Lost controller (pretty easy to handle since there is only 1 per group pull).
Auchenai Crypts: Phantasmal Possessor (dont spawn until group pull)

Group makup
Druid Tank 70
Fire Mage 70
Elemental Shaman x2 67
Restro Shaman 67

I know what your thinking.. why i am even doing Crypts :wacko: (lower city rep & hunter friend wants to complete). For the most part i will just burn down the class that does the MC first but, its not always that simple :S
