Our pets in MoP are working a bit different than at past. The stat chat changes are more dynamic. That means if u summon your gargoule and you get your Strenght increased while its summoned his damage output is gonna inscrease as well. That is both bad and nice in my opinion. Less rng dependant on some cases with unlucky trinket procs but becomes harder to manage to summon your gargoyle so it does its max damage! Also gargoyle casts seems to be 11 for each summon.
