Interesting, will have a go, and yea ping is not overly important in Arma as it's not a twitch shooter.
Aye, managed to do perfectly fine earlier on with 300ms ping, I think alot of stuff is client side so the latency is far less noticeable.
Today I was teamkilled while towing a black SUV back to my base (with an RPG no less), then helped build a large faction base that had 20 enemies coming for it in armour and we were setting up a defence in a construction site.
Far more focused on team work than DayZ, far more fun for me atm just because it's something new and not as slow.
