Not a lot of traffic on the Xbox end, but I can confirm that Vik is one of the few who actually know what he's doing on Xbox. I can think of maybe one other that can ever put up a fight the rare times I load into CQC.
I haven't tried CQC on PC yet, but I may give it a go next time I'm on.
As for open PvP, I can say that the skill level on PC is certainly higher on average than Xbox, but there are some exceptions. Lotta dual account fellas, too,
Thanks for the credit, but I'd wager that I'm rusty now. Haven't played in months due to my hotas being busted, and I refuse to pay $120 for a new one, when ALL of them start screwing up with ghost inputs in as little as an hour.
