Don't know about you, but I want to watch a tournament filled with some of the best players in Europe + maybe some top teams from the US.
No offence, but who cares to watch a tournament with 2k rated players just so they can have a chance at winning? Whereas if you have Trille, Blukstack, Minpojke, Zunni, Baten (to name a few good players from EU), people are going to watch for sure.
I'm glad that there's going to be more wow tourneys in the near future though.
A lot of good EU players aren't even on Outland (therefore can't join the tournament unless you join the guild with a boost character or something). Theres plenty of good players from servers like Sylvanas, Aegwynn and Ravencrest to name a few
