Overpower is your main aggro generator now, use it to hold large groups of enemies or for pulling mobs/bosses. Cooldowns are all there, vengeance is almost like sentinel, ToB is something like that, convalescence is convalescence, foresight is bad, bloodbath is bad but use it when you can, Unchained+berserks are obv dps stuff, Inner Beast is your main mitigator and it's actually a cd, use when you can for big moves(mountain buster, death sentence etc.) and lastly try to have maim always up, storm's path/eye too, depending on situation(need dps? use the second. Need to survive? use the first)
