With the introduction of U57, there have been a couple new bugs introduced as well. Below are some bugs that I've noticed, please add anything you may have noticed as well as submitting a formal bug report, so they may Hopefully get this fixed in a future patch.
Artificer:
Enhancements:
- Battle Engineer Cores no longer grant their universal spellpower while charging a rune arm. The buff shows for a second then disappears along with the spellpower it is supposed to grant. This was tested on a pure 20, level 32 Half-Elf Artificer.
Barbarian:
Enhancements:
- Ravager T4 Slaughter, does not provide the fury stacks on hit or crit, additionally the critical melee power does not work either. This was tested on a Razorclaw 12 Barb / 8 Fighter using handwraps, both raging and not.
- Ravager T4 Dismember, does nothing. No melee power, no bane damage, no effects whatsoever upon using Cruel Cut. This was tested on the same build as above.
I'll update my post with anything else I notice that doesn't get added from everyone else in this thread.
