Hero should make like a zig zagging maze in his wall so when he F2's the unit on hold at the end of the maze it takes like a whole warp cycle for it to get through
I heard Rotti , having a similar f2 problem, had devised a funny solution: you put a worker in the wall, with a shield battery nearby. It should hold for a bit until you react to reinforce it.
Possible Reynor GSL spoilers below: Was a bit sad for Reynor, he went out there , spent the money, from what i heard climbed high on the Korean ladder, so he must have faced top players there .. and then just couldnt get a map in the real thing. He didnt play bad i think, but he didnt play brillant either, and average doesnt cut it against Hero... Must be feel pretty bad for Reynor :(
in the GSL the group leader (hero in this case) picked reynor, who then picked soO who picked gumiho. Its a round of drafts so the groups usually end up pretty balanced. At any rate, Hero said he picked reynor because he wanted to play vs a zerg and reynor was the zerg he has the least rapport with. So yes it technically was because he was a foreigner, but not really in any unfair way. You could argue Reynor was even the favorite in the group to take the second slot behind hero, so this group really wasnt stacked against him.
