There's theorycrafting going on but there's just nothing huge to report because none of the sets have found a use yet. I've heard people are messing around with different dagger trait/enchants because of the status effect changes but META really is a science, it's not for sure that'll be the new META, especially because having daggers for trash and daggers for bosses is... crazy, honestly.

Had expected more theorycrafting in this forum after U41. Not even Skinny Cheeks has a guide for each class yet.
Skinny stated that he wasn't going to update until the next patch. As far as the new sets go none of them were better than any of the current metas (for PvE) so no biggie there. Might want to go with at least 1 charged on frontbar to take advantage of the buffed status effects. Charged/Charged is really good if you can stay above 50% crit rating with DW.
Some people are doing double charged and changing weapon enchants (absorb stam is really good if you already have good burning uptime, and disease can be good in trash). You probably want a templar DD in most groups now. You can do well with a parse dk and only 3 arcs if you want.
That's about the only real changes I'm seeing raiding at a high level.
There are people wanting to move EC to a sorc but I'm not sure that will catch on, as you wind up with half the group needing less optimal cp to make up the missing crit if you do that (as they only have shock and flame weaknesses).
