I'm not entirely sure what I should do during execute phase. I've seen and tried two different ways to go about it:
1. BT on CD, CS on CD, execute whenever rage is available.
2. Same priority list as >20%, building up 120 rage for CS and going for execute x4 during CS. Drop wildstrike completely, and execute to bleed off excess rage instead.
This assumes no rage income from zerker stance.
I don't really know which way is best. Having tried both, the end result seems to be rather similar and subject to crit rng on execute.
