don't worry, everyone gets pissed off by this @BeTe .
Yea the chickens around the cc make for an interesting gameplay situation, where the booming player has a delay before he can scout, and the rushing player can move out faster. I think after 3 minutes usually players have had a chance to check out what their enemy border is doing and prepare something, but a typical chicken rush comes in well before that.
One option a booming player has is to check for enemy cav with one of his ranged infantry, which isn't so bad in terms of idle time on the border. The downside to this if your enemy has cav he may notice and kill one of your units which could save you when the cav do arrive at your base.
I'd like it if something was done to nerf the chicken-rush, but I'm not sure what change is needed.
