@ADM-REIxSUPREMO It is suppose to be this way. This is the challenge of the entire fight. Who can heal faster and recoup and keep going. Sure aim and movement work but knowing when to pull out to shield and heal is a major function of the game.
Again imagine Gibby with this in his bubble. You could see quicker then gold armor heals or close to it when it was a thing. Making him much much harder to kill.
