You honestly think that Legendz will place better than Redemption? Legendz is good, don't get me wrong, but so are the rest of the teams in the top 8 - as well as a few outside of it. This year's Legendz would've made top 4 easily last year, but with the number of really great teams showing their faces this year it'll be a very, very close thing for Legendz to make top 4.
I agree with your pick for FBI Agency, though. Alot of people think that they'l be a weak team again this year because of their past performances, but with the lineup they have this year I think that they really do have a better-than-mediocre shot at 5/6, though they'd have to get pretty lucky to get a top 4 finish. As for MiR, I think they'll do fairly well. I might be a little biased, because some of my favorite players are on that team (just like Agency.) They're still a pretty big unknown quantity, though. They've had considerably less time to practice than the other teams, but they do have Saiyan and TN on the team, as well as Detach, who's not too shabby either. It'll probably all come down to who they get matched up with to play for the spot.
