I was a consistent crashee from NC model. Upgraded cpu/gpu/win7x64 - pretty smooth since then except when certain servers are running more slots than they should <..cough..why are foreign servers smoother than US for US players ..cough... but thank you for putting a server up regardless!>
Still get a crash from time to time, and I'm certain at some of those are NC-related, but I did not and would never put some moratorium on what assets people use unless the devs took it out. First of all, pub matches are not for blood or money; and second, it's not like I'm doing anything so important I can't rejoin and have fun (even if rank loss).
Let the devs do their thing and be grateful for what we have - and what we get when it gets here SoonTM.
