Probably going with this
Prefer cCarver to Grevle at tank. He’s no Li Xiu, but that uncleansable mana slow will hopefully be an annoyance in addition to the AOE damage. cBelith adds a 2nd healer with HoT counting as a buff, plus an undispellable buff to all. Tyrum and Poppy served me well in defense last week, so keeping them in there as the damage dealers while the middle 3 keeps them alive and slows down the enemy.
On the offense side, I just pulled Whacker and will level him up (sorry Gramps) since I have Barbarian emblems to spare
