Gladi I appreciate your concern with how the maps should be getting harder each stage, but I think the starting level is still a bit too low.
It's so low that the skill actually might not matter AT ALL. I can assure you that each and every OWC player can FC those songs 9 out of 10 tries, so your aim for them not to be consistency-oriented will be missed. I can only imagine it getting better later, but I already can predict some possible surprises when an underdog wins against a top team.
As to repicks, I am totally for repicks but only if they haven't been picked many times in previous OWCs, especially those from Semis/finals like Calamity Fortune or O.T.N or whatever.
