It's a balancing factor I believe. NMG and Adrenaline both act as a second layer of HP, while Resist shields is a flat damage reduction.
Loool I never even noticed lol gg dude. My guess is it's a minor trade-off for more xp, prolly for "balancing" since a lot of people did ***** about the heavy shields
Hmm another unannounced nerf the heavy assaults. I cant say I'm surprised considering how much the player-base complains. personally i think light assaults are worse. But thats just me. I would appreciate it however if the devs would stop nerfing things without announcing them.
