First impressions from me: I like it.
The armor lock can be used quite well. I had a couple friends over to play the beta, and one of them absolutely loves Guard, where the other fell in love with Airborne. Both of them use the abilities quite amazingly. Sword Base sucks, when playing CTF we couldn't find a faster way to the top than running the ramps, and it all looks the exact same so people were constantly getting lost. I did figure out where the shotgun (ridiculous) and sniper rifle (ridiculous) were on the map though. I really loved the needle rifle and the new AR, as well as the DMR.
Complaints so far:
-Sprint should last longer
-Grenades need to be nerfed some
-DMR needs to be given some power
-Stockpile needs to die.
All in all, I really liked what I played last night, and fully look forward to playing some more tonight. It's a lot more fun with a full group of 8 people, because you instantly get matched games, rather than waiting for the server to unfuck itself. I had 7 last night, my friends and I, and a couple of people we picked up.
Interesting story on the pickups, actually. We joined a game before we had a full 8 (we were running with 4 at the time) and SWAT got voted up. One guy said "God, SWAT sucks." My female friend who was sitting with us and playing said "Oh? Why is that?" to which the guy responded "Shut up, whore." I mean, is that really necessary? The guy then proceeded to say he was going to rape us. So, we were all in a pretty raw mood, and proceeded to play as such. The first kill was from the girl's husband on the guy that called her a whore, and it was a headshot. From time to time, we would pick up the other team's chatter, and apparently there was another husband/wife couple on that team, and they were reaming the guy, and he was doing the macho "I'll keep calling you names to make my tiny penis bigger" thing.
We kicked that dude's ass. Then invited the other couple to join us. Then Bloodwake joined in and we were doing pretty good.
But yeah, if anyone wants to play some later, add me on XBL. GT is the same as my name here.
