Whenever I play on EU (Granted, usually EU1) it takes me back to the two days I played before The Patch hit. One team huddled together for survival, the other team doing all the attacking. Didn't even experience rooftop bundle of sticksry either, no one breaks the ladders which I found totally cool although the sheer swarm of archers on top of said roofs were a bit daunting for a 200 ping 3 strength 31 agility peasant with a torch and a knife. It's very difficult to say what's better, but I do like DenBitre_Cooties because he plays very well in EU and NA servers.
Feels like more people goof off in NA but since I don't really know the EU scene I feel like I'm not at liberty to judge them at their clowning abilities.
