And the Stealth Soldier is not big and slow and they don't get shot by everything.
Shooting randomly everywhere is what people do to catch a stealth guy, what's wrong with that?
And what's wrong with this? If you want to regain your health, you need a teammate with you that invested an extra 200 credits and reveal your position for a while doesn't sound like a big deal compared to getting free health by doing nothing other than being a lone ranger sitting cowardly.
Someone posted it will encourage more passive play and SBH players prone to become useless, which is a valid point and you replied it's wasting time and not productive. That's the silly argument. Also, No need to target someone specifically.
SBH damaged to red doesn't need auto healing. They still have their laser rifles (good against everything), infinite ammo and have good speed. You either find someone kind enough to heal you, run with your tails in between your legs back to base to refill or fight till death like everyone else. No special cuddling for SBH. Not that I hate them, I love SBHs but self-healing is too much.
