Man, 1v1 gets me so worked up. I just manhandled a fellow toss player who was ranked 7th in his plat league, but it was still totally nerve-racking. I expanded pretty much right after I had built 4 gateways and not too soon after that he attacked with a sizable stalker force. He annoyed me a bit, but I had enough units (a mix of zealots, stalkers, and sentries) to keep him at bay. My economy was just rolling along and I should have built a few more gateways, but I built a forge to start upgrading and a twilight council to upgrade zealot speed. He then did a prism drop, which I took out ridiculously easy with barely any probes lost.
So then I rolled over to his base and just wiped him the fuck out with my 2 weapons upgrade and speedlots and guardian shields. He had only *just* expanded. Maybe I am a diamond 1v1 player, but I just haven't played enough 1v1 to get promoted out of gold yet lol.
