So far Kraken Beers have shown no sign of sink. Plus they have such a nice profile picture, look at that lil fella having a drink of brewski. I think another persons insight on a sink or swim is necessary. Not to say you are wrong, but going off 1 list has its bias. If I felt I had the knowledge to do so I would have.
Kraken - Sink (clearly too focused on the center, painfully obvious they have no clue how olympus works, implosion eminent)
Vikings - Swim to Win
Really solid group of players. Had 800 birs in a Kraken IA city yesterday so they clearly aren't being pressured (at least as of yesterday) will have to see if Kraken can pressure them going forward. Top defenders by a mile, and probably strong leadership (can't say for sure, but lots of recognizable names).
Doom - Float
Not bad, but not really impressing so far. Stats are just worse than Vikings so I'd personally take Vikings over them, but they do seem like they will stick around and could definitely play a role.
Outlawz - ?
Don't really know anything about them so I won't comment.
Undauntonauts - Swim (very gently)
Dark horse. I wouldn't predict them to win, but I do think they are stronger than the stats suggest. Lots of good players and it's a long game so they should have time to develop.
Dirty Dancers - Fine
They don't really have enough people to be a strong team, but they are doing alright with what they have.
