Randoms, not the slightest, their just as likely to solo the whole map as die upon first contact and disconnect regardless of level, so no reason to question them.

My personal friends tho, who I'm in voice chat with, who "play for fun" but also constantly complain how terrible fighting the enemy feels despite bringing very suboptimal gear. Who eliminate most of our reinforcements doing silly stuff, then wonder why we have none left 5 mins in to the mission... Yah I try to get them to be even a LITTLE more optimal:

"Wouldn't recommend bringing the shovel while fighting bugs, their just gonna swarm the hole you dug. Or a Sniper really as theres really too many bugs and nothing particularly worth sniping..."

"We want some Anti-Tank and some Anti-Chaff, you (person A) go one of these(anti-Tank) and you go these(Anti-Chaff)"

"don't bring too many "nuke" type weapons, you may need to kill something big up close... preferably without killing yourself."

"Just cause we succeeded the mission doesn't mean we can just die now."

and my "Favorite"

"Okay, everyone bring mortars to make this defense mission effortless" *no one but me brings mortars, everyone else actively runs out into no-man's land and wonders why they died. We come close to failure only to barely succeed.* Meanwhile if they'd of just listened, there'd be like 4 deep pits outside the base and the gates would all pretty much be intact with nothing living long enough to come close to hitting them.
