You can still kite no problem, however you need to make sure a ranged hits it with a Rank 1 spell so there is secondary threat.
TL;DR: If you are pally, you are not the off tank of this fight, you are the main tank.
Get initial aggro, rest of melee stays away. When you are conflagged, Drak will run towards healers/ranged, warrior/bear can taunt, once conflag wears off, it will come back to you.
Repeat.
