WNx Chicago is the only one that people seem to use on a regular basis. I do wish more servers were used.
Just to say, 24/7 LTK servers are a great, great shame according to my tastes and opinion. Or 24/7 anything, really (but especially no skill, back-shooting mode aka LTK). Gotta love the random gamemode thing. Especially once you guys get the other modes implemented into the game. You get a little of everything. Nice.
Also, LTK on Cradle should be a crime.
I don't really have anything meaningful to add...
(brag time)
...now look at mah (wnx server) stats!
I have the highest accuracy next to VC (out of people who have played a decent amount of time). Aww, yeah!
