Less what they say and more what they do, but the last game I played wherein the TGI with the Avenger X spent 15 minutes trying to kill a geth prime on silver(we'd all bled out through stupidity or...well, stupidity. Honestly, there were only like 3 enemies left. It shouldn't have been that hard.)
Problem one; he did not know how to cloak and then fire. He never did it. Ever. Not. Once. He also insisted in overloading the prime over and over again while missing wildly with his avenger. Good thing it's pinpoint accurate in short bursts! Eheh...heh...eheh...
But at least he could use it to avoid taking damage, right!? No wait, no he couldn't. He proceeded to use at LEAST 50 stim packs by not using cover at all and getting nailed time and time again as he ran through the open from ammo crate to ammo crate.
Finally, after 10 minutes of this pain, one of the bled-out teammates comes on the mike. "Dude, do you have any missiles left?"
Ten long, quiet seconds later; "Oh. Right." Pseeeeeew--Boom!
The worst part; we had already beaten wave 10. He was literally doing that entire exercise for the sake of 2000 credits and a few thousand extra XP. And then he died and bled out before extraction.
Good show, old boy. Good show.
