just to inform on a few issues or new game mechanics with patch 3.x to help PitBull go forward.
Aura Debuff :
the default blizzard ui show self Debuff with a different size so that you know your debuff is on, you can have for example different frost fever on target and still see that YOURS is on. PitBull doesn't seem to differentiate btw your group debuff and yours if they are in the same category.
suggestion: add a self debuff check so that it only shows yours.
Vehicle Mechanics :
the default blizzard UI when entering a vehicle is Playerframe become Petframe and Vehicleframe replace Playerframe, Pitbull for now is Playerframe stays on Playerframe and Pet Becomes Vehicle. The blizzard default one is better because Player don't take damage in a Vehicle until Vehicle is destroyed.
Malygos Event (raid):
in phase 3 of Malygos everyone is riding a Drake (vehicle) you get an ability that puts Combo Point on Malygos but ofc PitBull doesn't show any combo points yet.
Suggestion: enable the combo points module for "vehicule mode".
