Watching IEM Katowice right now; Azubu Blaze just demolished Meet Your Makers. So let's have a pro teams discussion!
For Asia I think my favorite team is World Elite; Ezreal is my favorite AD carry and Weixiao is probably the best Ez in the world to watch. I've always pulled for Curse in NA especially after they picked up Voyboy, but I thought Brunch Club and MRN were really fun to watch during the S3 qualifiers.
And in Europe, well, I love CLG EU or whatever they're calling themselves now, but you can't deny how fun Moscow 5 (or Gambit Gaming now) is to watch.
