I'm starting up my first Multibox, going right to 5man...

I want to do instances...
I want to do Heroics...

I currently have a 70 (or close) Druid, Priest, and Warrior.

I was thinking of:

Pally (Draenei F)
Shaman (Draenei F)
Warlock (Gnome)
Warlock (Gnome)
Warlock (Gnome)

I really like the idea of running arround with Succy pets up with the Draenei Pally/Mage...
However i'm worried that I will not be able to do heroics with this group because of lack of CC.

I really dont want to do more than 3 classes (thats more than enough already)

Mage Mage Mage setup would have the nice bonus ports, drinks, and AoE (I'm multiboxing on one system, so I cant AoE attack with Blizzard... but AE would work just fine)

Basically, Can I do heroics with WWW + Tank + Healer... or do I really need MMM + Tank + healer
