Well all of the other supers allow death. Everyone runs to a Gunslinger super cause they die if you shoot them. Everyone sharpens their shotgun when a Bladedacer pops a super. As long as you don't allow a Sunsinger to melee you all is good. There is no warning for the rest. I usually sit and stare at Defenders when they pop a bubble. So you don't have to run from any other super. I guess if you could run from FoH, Vortex, or Shadow shot you would but once they are done they are din.
