Teleport (still only on 1st and 2nd attack? How large is the range?)
Movement speed reduction
attack speed reduction
heal + CC to interrupt or peel for a weaker buddy getting focused
immunity + dps
Both def spells end of with some offence too
Tail kick fire ball to peirce groups and take out targets in the back
12% more dam and mob 10% dam reduction
All three passives def.
This spec seems to have it all. Although lacking mobility possibly if the range on thunder clap is too small. Otherwise I would think very viable for late game.
