Oh and on the matter of the shields, I was turning them on to save my ass even if it would only block one shot (for the acu). For the other shields i was turning those on right away knowing that I could use an engineer to regen them, seeing as i had no other shields at that point I really needed to get those up asap and didnt have time to wait for them to regen....
There was a period of about 2 minutes where your commander shield was on but at 0. You should have been charging then, might've lasted you a few more seconds against those loyalists.
