I explained what I meant for you in my previous post. I'll say it again. Out of the mobile supers (arc blade, golden gun, radiance, storm trance, HoS), HoS can get the most kills (best offensive mobile super), while enjoying the most defense (55% damage reduction), in addition to health regen from (ranged) kills. That's what I mean by the best defensive mobile super. Does that answer your question? If not, I can go into more detail for you.
