My playgroup doesn't sit in missions longer than two hours at the most. Having more power strength is nice but unnecessary for that amount of time in my opinion.

More armor is eh, if it's your jam, get you some armor. But I haven't had any survivability issues.

My Weapon Choices:
Primary: Supra Vandal w/Entropy Burst - It's good at burning down nullifier bubbles and keeps energy topped off as if that was an issue.
Secondary for short missions: Mara Detron - Detron is a beast
Secondary for long missions: Pox - Spread the sickness
Melee: [Lesion] or a Status built Plague Zaw, but who am I kidding, the [Atterax] is welded in my hands.
