I'm still here, playing most of the time alone on the server lol
Lyriam is the only other player I've seen around this week, but that's solely because he/she's running the game in background during work for mag purpose I believe.
Personally the addiction factor faded away a great deal since I got Yas3k. There is no other drop I absolutely want atm. Yas7k is an insane drop since that's on Sinow Zele who are bitches to hunt and only shot range.
The only other fancy rifle I want to try and can do on my ID is Holy Ray, I'm currently at 17 Del Ra Lie for a 1/37 rate.
Not feeling redoing the Gigues anymore. PW4 is the quickest way to farm them, but the Ill Gill in Ult is another bitch. I've done this on the OG PSOBB in PW1 but it takes way too much time compared to PW4.
I guess I'll still be here until FM16 eat most of my time and eventually Xenoblade X, if the game is strong enough to go against FM.
I'm not really doing mag raising (anymore), but just stuff that is low complexity / danger and can be walked away from at any moment.
As for the general server population, yeah it has dwindled, but it is the middle of the week and you're relying on people that are available in your western-european time zone. Asami is on vacation, so that's one regular that's no longer present, and Tom hasn't been on as much this week. Those are the only two I know off the top of my head that are regulars and close to your time zone. As for the others... Neon, as mentioned, is being kept busy by class and homework. Soldat generally is on later at night, and I don't really keep tabs on Hauzer, As for the rest, they're either on less regularly, are not ult capable yet, or both. (Edit: Oh, and Frosty is MIA.)
We never regained those that we lost to MGS, and at this point I have my doubts we'll ever see them again, so my hopes are mostly pinned on the current batch slowly making their way up the ranks. Failing that, we'll need some new blood.
