Le sigh. That argument has been brought up before in this thread, and the response is still the same: this thread is about the time it takes for shields to replenish (and reboot when failed) in the very case that you have got some breathing room, or even entirely withdrawn from a fight, not about the fact that you may eventually have to do so in the first place. And as I just said, as long as you are still being hit, shields to not regenerate at all anyway.
"Le sigh"?
OK.
