SZ, I'd just give it a go, see what its like. Matt and I have got all our stash tabs on US, so EU is where the "challenge" is for us. Since most of the existing EU people aren't on, and joined other clans, we joined this other group. There seems to be a few hurdles to get in the door, but overall it sounds like a mature and active group.
I'm from New Zealand. I get more lag on EU compared to US. If I'm doing certain moves like Vault, I get some rubberbanding sometimes, but overall its quite playable. I'll have to add you as a friend so we have the option to play (assuming times mix). I won't go too hard this time. I'm not overly excited and don't want to risk a full burnout.
