By my count right now, we will have ~13 IM teams. This is an estimate based on the people without teams and stuff that I've talked to about it.
If everyone I've talked to about it + malicious activity + all the other "confirmed" teams play, there will be 16 teams in IM. I'll only be comfortable if 3 more teams COMMIT to being formed, though. We're super close, just DO IT. I'll help you sort roster hijack stuff. There is definitely a team or two of high-top IM people still lft. Definitely 3 teams total. Just do it. :)
If we do keep IM around this season (and it still is "if"), we need to have a serious discussion as a community about why 70+% of open moveup teams die when they get to IM so this doesn't keep happening. Like... why would you not want to play with better people against better people?
