While pressing to block or already holding block, there is a delay and/or intermitment applying of block.
It almost feels as though the mouse button is broken and not registering the click - however I have tested the mouse using various software and other games, and the lack of repsonse/intermitent response is only happening in ESO. Other players I know are also experiencing the same problem.
This is the latest in a long line of block bugs, and it is not overstating to say this is game breaking. One unblocked heavy attack = death.
Can I make the suggestion, that you consult the player base on the idea of making block a toggle. It would surely put an end to this persistent problem with block.
