Hmm, do AI autobombs act properly? I'm not sure why it thinks there's a difference between martyrs and autobombs.
Though even that wouldn't be great, I can see it now: cheesing AI martyrs by having them detonate on a single scout.
The two are coded differently, at least on the tooltip.
The autobomb has an attack, and no where on the tooltip data does it say it self destructs (while it does on the description.)
The martyr does not have this direct attack, but on the list of attributes it says it does damage on death.
If you gave the martyr a very short range (2,000) attack as its ai variant you could prevent both cheesing with scouts and allow it to hit blobs (because its tractor range would prevent it chasing units endlessly once caught.
Also, the ai in general makes them much too slowly. With a 4 HW game on 8.0 they seem to make one per world, and to regen them takes several minutes.
