I did but all of those for the moat part are extremely situational. It depends on the way you are facing, the layout of the map, the skill level of the players you are facing and some more. And I don't think that I have ever survived a nova bomb in my bubble as you say that you can. Sure Fist can shutdown supers like bladedancer and maybe radiance but the rest will completely decimate you before you get close enough to activate it.
