I've noticed something strange lately. When I play against Zerg - especially as Terran but also as Protoss - the opponents surrender really fast, even when they have a good change of winning.
Now I might understand if someone tries to cheese or do a Zergling rush, fails to come past my wall and then quits. But most of the time they are playing more 'legitimate' strategies, and still quit at the slightest resistance.
Last time, the enemy had roaches in my base, and Broodlords and who-knows-what in front of it, and was killing all my workers. I had recently engaged with his troops, so I had no units lefts except for some Reapers. I was about to give up, and just for fun sent my ~6 Reapers to his exe. The moment I started attacking him, he left!?
In some other games, it was sufficient to send 2-3 banshees over to make the opponent freak out and quit.
I never experienced that aginst T or P. Its really unsatisfying that I rarely get into endgame against Z. I barely even remember the last time I actually destroyed a lair or hive.
Why is this? Do you so easily get into a position from which you cannot win as Zerg? Or are Zerg players just more easily frustrated? ;-) (This is upper bronze / lower silver btw..)
