You'll assume wrong. In general most of the situation you're presenting is very specific and relies on a lot of assumptions that don't translate well to common play from my experience.
It does not. You need to wait for the server tick, which can be instant, or it could be as much as 3 seconds. You've simply been lucky. (For posterity, most things operate on server tick; notably dots and ground effects like CO)

And if it isn't your problem, then what is? Because Refresh is still mp, it doesn't magically give you more MP the later in the fight you are. If you aren't 100% mp, then it's effective mp.
