Ok so I decided to hop back in game today to check what's new with the DB update but unfortunately after 2 hours of playing in IC i just had to quit to make this post. The problems I've encountered so far:

1. Items sold by IC Vendors have no prices on them.
2. Gap closing abilities seems almost completely broken (again). Sometimes my characters hides his weapon while performing a gap closer. Other times it "flies" to enemy even if there is a pit between us. The buildings in IC have many holes in the floor, i was standing on the one side and the enemy on the other. I used Invasion ability and my character just performed a run in straight line completely ignoring the hole in the middle.
3. Idle stance from weapon will stay the same after swapping. Example: after You swap from 1h+s to 2handed your character will hold his 2h sword like he would be holding 1h+s.
4. Sometimes my ultimate abilities would not fire off. When I'm in the middle of the battle and will try to cast ulti it will just start the animation and cancel itself out after like 0,5 sec to perform another ability instead. Is it caused maybe by the "animation priority" change made in this update ? I did not have these problems when testing on PTS so I'm not sure.
5. Abilities that should stun don't work half of the time. Sometimes the stun works and sometimes it just does nothing (no, the target did not had stun immunity).
6. I'm quite convinced I saw one person respawning in IC district controlled not by his alliance but I will need to test it further to confirm it.

I would say that animations, weapon swapping and casting abilities feel a bit clunky overall but i have no idea why cause like I've wrote earlier, it felt very smooth when testing on PTS. I hope my post will help to confirm and eliminate these issues.

Also please feel free to post Your observations if You found any bugs.
