Personally, if you are a big fan of 2's and 3's where you need major burst dmg at the get go, and you are BM a trinket like Bloodlust Brooch is key for your 18 seconds of fury. For longer fights such as the ones 5v5 brings, I would go with the Battlemaster's Determination, will help your healers (albeit just a little) focus on the melee which are probably getting more dmg and give you a little more sustained dmg (albeit just a little)... =)
