Eh.. calling the NA Meta boring I can see an argument for.. but I don't know if you could really call the EU Meta "varied" as much as EU teams are constantly looking for the next OP comp to counter the typical setups. They certainly try a lot more things but I haven't really seen any teams stick to any non-typical builds long enough to master them. I've been seeing that a lot more in NA where you have guys like Jumper who come up with a build that's a bit different, then mastering it and applying it to team Strats.
Well, that's why I said *a bit* more varied. At the moment, the game itself isn't in a state, where it can support a lot build diversity. Even the devs themselves are confirming every SotG, that there are like 2-3 builds per profession. And 2-3 ain't "a lot".
And as I said, I can't comment on the "NA meta vs EU meta" topic, because I haven't played in NA. I said only what I've heard from friends and people I'm playing with.
