MapleSEA got Tempest

Fair enough. I think they'll do it though, the sh*tstorm they'll get if it is fake will most likely persevere them into doing it anyway.
And I'd definitely like all exclusive GMS content, mainly proper KSH and non-nerfed LHC. Aliens would be nice as well.

I'd say at least half of that is confirmed, but I'd prefer for them to do it bit by bit to avoid major issues as many players are one major frustration away from quitting.
