2nd, 5-8th and 5-6th might not be what they wanted but they aren't bad placements. Still grand/quarter finals. The only bad one was 9-11th.
Skadoodle went crazy during the major final, he got MVP just in that match, and he still put up decent numbers while that roster was together.
Unless you provide some sort of source to the "it's him or me" thing, I won't believe it, because I've never seen that before. Pretty much the only clip I've seen of stew complaining about ska was at the major final where he was complaining to Valens about communication, and they won that anyway.
