Well, there's no real choice about getting that 10% trait first and foremost, my initial plan was to 4/4 BC, RB, and enraged dmg.. not so sure, now. These are my thoughts:
The first trait giving rage for RB crits is good; for as long as we talent RA and insta-dump with RP, RB will gen a decent amount of rage to get back up to max in order to dump again. However, whilst we're still using DoS, this will be slightly diminished as we'll fit fewer RBs per BC, although having CoF helps this ofc.. but again, if we're perhaps not going to be using DoS forever then likewise we may not be using CoF, either. Just a thought, not a fact. That said, by the time we're possibly no longer using said trinkets, we should be a fair way into the new artefact knowledge and AP should be flowing again.
From what some of the chaps on discord have been saying, the golden trait is great; +300% AP is huge.
