We go 2 - 2 - 3 - 3 - 4 - 4 if we get that far on tank transitions and make sure we're popping 1 of our cooldowns on each one. We also hold dps at 36.5% roughly and wait for a slime to come out. Burn it, slurp at least 1 if not both puddles and then push him to Phase3.
Our kite path may be different than others also as the tanks run to the starting door and wait for putricide. DPS stands spread out in the middle and doesn't have to move much as we do a clockwise path. We only move Putricide when either a slim puddle drops or the gas bombs hit so you should almost be at the table when he dies.
Make sure melee are hugging his ass when the gas bombs come out and range avoid the damn goo. If multiple people get the +hit debuff it's pretty much a wipe.
