I actually really like the idea of a MGE tournament/ladder/league, maybe that's what you can make this into? I don't think it's necessarily a good idea to make an alternative for ETF2L when it's very prosperous, ESEA-O is also probably not going to die as long as teams are formed (direct quote from tri) so that idea should be scrapped. I know people have wanted an MGE sort of league or what not and maybe this is a start. Also like previously said, SOAP DM could also be made into a new ladder maybe, sort of like teams of x amount of players fighting in DM and first to x amount of kills wins or something of that matter.
I'm for it, your initiative for wanting to start something sits well with at least me.
