vs anything that isn't forge before core I've been using day[9]'s anti-4gate 2gate-robo build. If it's good enough for him, it's good enough for me (and anything is better than 4gating).
Warpgate really needs to be higher tech option with some kind of drawback (does anybody remember the hotkey to turn WG's back to gateways? yeah). So toss looses a few early game timing attacks, I'd be glad to loose them if it meant killing 4gate.
