I played my first daily last night, and it went fine. I went in with a friend of mine and 2 other randoms. We breezed through it, but there was quite a bit of lag. One of the randoms was from Australia, so that was likely to be the problem.
I got a legendary SCAR-L, which is a great gun. It had a 63K base DPS, and that was nice. After I attached some mods to it, it went up to 112K.
I was also helping my friend get his stats a bit of a boost. He's has been playing longer than I have, due to the nature of our work, but his stats were considerably lower than mine. When I logged on last night, I was at 107K DPS & 68K Health, where as he was 50K DPS & 27K Health. He was mostly focusing on Armor rating, rather than fine tuning his armor to compliment his play style and stat focus.
EDIT:
I also had a great time in the DZ. I've never seen so many Agents in one place. I swear, it seemed like there were close to 10 players running around the same extraction. I'm not sure what the DZ instance limit is, but it was nice to see. One of the best parts was one someone accidentally went rogue and tried to run, all of the other Agents chased him down, and then they accidentally turned rogue. In the end, every one was rogue. It was crazy.
