It will provide a challenge as it seems that in Legion the popular mechanic is to constantly toss pools of fire all around the room to dodge/avoid.
But that is a strong setup.

I have a friend who is currently leveling Dual prot paladin + 3x BM's He is in love with it.

For the most part he has always been partial to the 5x Hunter teams.

I run a lil bit of everything myself. But my WoD teams of Tank/3xHuntes/heals where some of the strongest for 5man content.
