I was in a match against 4 Terran. It was very short, considering they all sent their SCV's and forgeted over a base. The owner was too incompetent to realize that his probes could attack back, so it was 3 groups of probes vs. 4 groups of SCV's.
After that, I was victim to 2 different Protoss cannon rushes. I lost both times.
I got pissed off. Normally, I wouldn't stoop to such a low level, but I'd had enough of being victim to that tactic.
The next game, there was one player on the other team who was lagging horribly. First chance I got, I scouted him out and planted a pylon on the corner of his base. He whined and complained when my cannons eventually overcame him.
LAG loving FIXED.
