Another issue I'd hope they could address is the horrendous server lag between activating a skill and actually having it work. As an example, if I cast cover or Hallowed Ground, I can see the skill go off, the button greys out on my hotbar, but do I or my teammate get the effect? Nope.

They did it with mudras. Why not other actions too? I'm sure benediction and lustrate could be done this way too.
