Well, it would hard for him to control his groups, yes. But... I'd love to see that against corsairs
On a side note, you can't have 4000 overlords
Maximum units is of 1600 (200 limit x 8) in the entire game. Hence why sometimes, in money maps, zerg versus Protoss, it is often that that cannot create more units message shows up. Protoss use carriers (lots and lots of interceptors), Zerg build around 50 hatcheries (150 larvas
).
Nice try, though
