I 2nd ano here.
Micah's suggestion is good - however I don't see why we have to go to all this hassle just to defend players from early rush. Take an awake SC if you are afraid to be rushed. Rushing is part of the game and while I wouldn't have minded hiding the capitals I don't think it's a good idea given the consequences on end game (the original suggestion) or annoyance/overhead (the obvious draw back of Micah's otherwise excellent suggestion).
I say we go as planned.
Micah, now that you've made a visit here - care to join us as the 19h player?- (Although this will probably significantly drop everybody's chance of victory
)
