Had the best experience last night that I'm dying to share, so here goes.
I'm still level 7ish (having a 9 month old to take care of I'm surprised I'm not lower level) and it's 10 PM Wednesday night. I had done a few side activities and tweaked some mods and my loadout when I decide "Ok, I'm going to go do that trainyard medical mission". I haven't really tried the matchmaking yet so I figure I'd give it a try.
About a minute or two later, I get a hit and join up. Luckily they were still at the beginning. A quick glance at the party list shows me they're level 5-6. Not sure why they're so underleveled, but whatever.
So we make our way through the mission, and we are just getting dumpstered left and right by elites with flamethrowers. In one of the big firefights (hah), a huge wave of enemies engages us from the front, and we get flanked by elites every time and killed. After a few tries, I get up on some high ground while the squaddies lay down some cover fire, pull out my marksman rifle, and explode a few normals in single shots, using the turret from odd angles to cover weird pushes from the enemies. Ok, awesome. We made it through to the boss room...
...And then proceed to wipe about 8 times. After the 6th or 7th, someone quits, and we try everything to get the encounter clear. I switch skills time and time again. Smart cover doesn't work. The sticky bomb isn't really doing it for us. Scan doesn't change anything. Every time, the same result: we take out the first wave, then the boss wave shows up and we get baited into attacking the left flank while they sneak around the right. We attack the right, and they all bunch left. We try getting high ground, and spreading out, they cut through the gap we leave, stranding our sniper, and cutting through to take us out.
Finally, I've had enough. R1: Turret. L1: Heal. Let's go. It's just the three of us, like I said. First wave down, boom. Second wave starts up. I hit the cover on the right side, taking shots at anyone trying to flank us. A quick glance to my left shows that the elites are starting to bunch up and push that side. So I toss my turret on top of our rightmost cover, and pull out the marksman rifle. I see an elite that's low on life, no armor. Tap out 3-4 shots without even thinking, and he goes down. Same for another. Tag a normal with low HP. Shit, right flank again. Barely manage to take down the next elite and heal up with a medpak lying around that I happen to scramble across.
Then I realize it's gone quiet. It's just the boss left now; I see my squadmates taking shots at him. One gets hit by him and his turret and loses a good 3/4ths HP, and I get an idea. Flank on the right. Good, he didn't see me. They're keeping him busy. I check my skill indicator, and my turret comes off cooldown. I'm flanking him now. Grinning, I toss the turret on the cover right next to him and start firing. He freaks, backs off, and jumps behind some better cover, with my turret rattling off shots nonstop.
And then I see it.
"Suppressed"
My character looks down his scope once more, lines up the shots, and he goes down. Finally, he goes down.
Many jumping jacks were jumped that day.
Then I looked at the clock and realized it was 12:30 AM. Shit.
