Been noticing this bug a lot the last couple of weeks. I can't cast any skills when I run out of stam. This includes heavy attacks and mag or health-based skills.
I've seen this occur on DK Tank, Necro tank, and stam arcanist. A friend notices it regularly on his stamina arcanist when running coral and dumping stam.
We can fix the bug by standing completely still and not pressing any buttons, e.g. taking our hands off the controller for a few seconds. After a few seconds stam starts to regen and we can play normally. But if we try any controller inputs, it extends the wait time to begin recovering stam.
