This is well known bug, and its been more then 4-5 months in the game, still not fixed (Not my img)..

During summerset this was happening 1-2 times during 3hours period of raid, in wolfhunter this just got worst, people are getting stucked in block in pvp, raids etc.. And now in murkmire its almost every single trial.. At first sight you think you can just ignore it because it is "visual" but, it has huge impact on your dps and your block..
While your character is stuck in block animation, your light attacks will miss way more then normal, like you can aim at target directly and still your light attacks wont register at all, your skills wont cast correctly if you do rotation fast, when you do rotation at fast phase and you try to block some mechanics, game wont register your block and you will die..
From all bugs/bad performance of the game, this is most annoying thing right now for me, it ruins game experience even more then bad fps or ping..
This cant be fixed by reloading UI, this can be fixed tho by traveling to other player (from group or not), or traveling to another zone, but at endgame raids, you cant make 11 players wait for you while you travel to begining of the trial then run back to current boss..
From what i have seen there are few things that cause this bug: Block canceling any skill might cause this (higher chance on cast time skills like channeled acceleration), doing rotation LA+skill and if there are lot of mechanics that you need to block so you do LA+block more often.
I submitted ticket, but all i got from zos is that i need to remove addons from my folder, and im not sure that addons have anything to do with block..
Any idea what cause this problem or when can we expect fix?
