I ask my Tank friend whose been a on since ARB Beta, and he couldn't tell me why or who it for.

I am unsure how and why it's used on single target when as a MT, I don't use it and for OT 10s is not a long window to be proactive with it. I tend to use it, when a person is raised and a big move is coming; such as titan weight and stomps. The CD on it is kind of long for a High action group and the 10s duration is not going to help 2+ members for that long.

So i need the community help on how do you deal with the move "Cover"?
