I don’t see any balance changes in the patch notes. So I don’t think they need to rerun the gearing strategy for changes specifically.
I do, however remember Yellow saying something about the talent rings are causing some problems. He said he had a proposed fix for the issues people have been having with it. Unfortunately he wasn’t able to rerun the strategies before he left for vacation (that or they error’d out during running)
EDIT: Could you provide your Export String and I could take a look at what’s causing the huge DPS decrease.
