Using critters?

What can critters be used for? I had some ideas but what else is there?

  • You can follow them and autmatically explore the map.
  • You can suround them with DT’s then push them into the enemy base and make it look like its attacking stuff.

Incredibly useful I know, anything else?

Oracles Revelation for some extra vision.

Prematurely releasing Carrier Interceptors or Brood Lords Broodlings from a safe distance.

If they are within distance with the cooldown ready Zealots can use critters to get away from units with Charge.

It will be anything except reliable but you can use the Raven missile on them to blast enemies if you can predict where they will move their units.
