It's obvious you don't play with a warlock. We don't get overshield, we just regenerate our health once, then we go back to normal recovery. This is only if we ahve both greande and Melee fully charged, so we nust hold onto our abilities if we want to get the most out of our supers. Then there is the fact that if you don't have the selected perk the super actually last half as long. Basically running the stormcaller we do get a few limitations in our build. Eitherway if you have not noticed all Arc builds are centered towards close quarter encounters. If anything the class is fine as it is, no need for a nerf nor a buff.
