Pet Tiers and Acc! (Thugs in Specific)
I slot a full Blood Mandate set and call it a day
Arsonist is your big damage dealer, and 2 levels lower than you, so I would say not to skimp on ACC. I wouldn't want to play with less than 1.50 accuracy. I usually slot it into the high 1.70's or low 1.80's. You can get that with 3 parts of level 29 Blood Mandate set. It doesn't cost that much. I don't know what you plan to do with the extra slots, though.
What would you consider to be the 'minimum' amount of accuracy to slot in a Tier 1 pet? In this case I'll have the enforcers dual 2.5 to hitbuffs (+40% from two Hami-O Cytoskeletons), but I myself do not have tactics.
