Gateway > Warpgate requires no resources, just a few seconds. The upgrade to do it costs 50/50 at the Core.

That'd take 20 seconds anyway. To make it a gateway then make it back into a warp-gate. So... if that does remove the cooldown it's not really worth it unless you're some sort of crazy APM fiend.

I hadn't noticed it takes 10 seconds to switch to Warpgate now, and reading the OP post again, it seems like it doesn't really remove the cooldown (which would be a horrible bug).

But it should be true that the first time you switch to Warpgate, if you just produced a unit from the Gateway, you can get another one very fast after switching to Warpgate, as it makes the unit first, and then cools down.

Still, you have to get the minerals to do it, as units aren't free, so i wonder how much impact can this really have in the game.

I've been testing out going fast warpgate with something like this

Pylon
Gateway
Assimilator
Pump out zealots until Warpgate research is completed
Cybernetics Core
Warpgate research (with a chrono boost to speed up research)
Pylon
Another Gateway
Pylon
Turn gateways into warpgates and pump out 2 quick zealots or stalkers depending on what your oponent is doing
Another Gateway -> Warpgate
