I've tried searching, but 't6' is too short and both '2t6' and '4t6' return no results.
Playing with RAWR, the Feral 2t6 bonus was near godly for cat dps with 4t6+2t7 being best-in-slot for dps with mangle spam. As of the 2.1.4 update, it rates both the 2 and 4-piece tier 6 bonuses much lower. The 2t6 bonus is now rated around the same as 2 non-set iLvl 200 epics. The changelog made no mention of any formula change.
Loading my character from the armory in both 2.1.3 and 2.1.4 (wearing 4t6) I get these values (socketed with blue-quality gems):
2.1.3:
- Thunderheart Cover: 196.81dps
- Valorous Dreamwalker Headguard: 148.65
2.1.4:
- Thunderheart Cover: 196.67
- Valorous Dreamwalker Headguard: 210.52
What changed that suddenly made the t7 hat jump over 60 dps, not even counting the set bonus?
EDIT: Found it, there's a post in the general class mechanics forum (
