That’s the PASSIVE regen stat. You get considerably more super energy than in the previous sandbox from simply dealing and taking damage, alongside getting kills. Personally, as long as I’m continuously getting into engagements, I’ve barely noticed any difference. I still get 2 supers easily every game in PvP - mind you, that’s on top tree dawnblade, second longest cooldown timer - and on occasion three. Aka - actually try it out, don’t just say “whoa that stat bruh” and call it a day.
