second, actually i am using the heirloom trinket, should i switch to a pure stats trinket (with versa or crit) 840+ over the heirloom one, or its still better?
You'll get your answer faster checking out other outlaw threads tbh. Sims seem to be broken for outlaw. Mastery shouldn't be that high but it seems like it ends up 40-50%+ for most people just because of the gear thats available atm.
