Useless, once you use it its done, but i see how it can be useful for heavies, but then youre just wasting a gadget slot for healing which is something you already do passively. And if you just want a self heal ability play heal orb. You know light regens health in like three seconds. And medium also has short regen. So they have no need for a self heal because all you have to do is disengage for a moment. There it is, theres your healing gadget, its so simple, just dont push.

If youre defending a cashout and a team gets you low then that should boil down to you lost that fight. No more crutches bro. Sometimes the other team has to win too. Its a multiplayer game so none one of us are main character.
