Two useful late-game units that the AI doesn't know to build

[ByrelMitchell]

I've had to do a few late-game fights against a builder AI who has outscaled me, and they're generally viciously effective in unit choice. However, there are a couple units that are really useful I've never seen them build:

• Drop Probes. The AI is really good at using probes, and pretty good at using drop units, but never makes drop probes.
• Dissociative Wave needlejets. Having Dissociative Wave on your needlejets lets you ignore AAA on defenders, which is a HUGE deal in the late midgame and onwards.

Not a bug, obviously, but a suggestion for improving AI performance.
