I imagine a well-tuned "philosoraider" ability on Glaives would make Pyros fail on fight move.
By "philosoraider" here i mean the emergent fight-or-flight decision technique pioneered by aeonios
in ZKGBAI and quickly ported into every other competing ZK bot, which works this way:
1) All enemy units emit threat auras onto the threatmap that the AI uses to path for raiders
2) Controlled combat units emit confidence auras instead
3) If at a given point, confidence exceeds threat, assign nearby units into an ad-hoc squad and commit to an attack
This means that several glaives circling around a Lotus, while individually unable to overpower the Lotus, and while handled as individual raider micro-squads, will know to merge into an attack squad. And similarly, insufficient numbers of glaives will not press the attack (though tuning that
is something that has so far been done only poorly and manually).
I think that while circuit does use this technique, it under-uses it, which is why it's a bit hard to notice that this happens. Circuit prefers to keep its raiders in reserve and find juicier naked targets rather than accept losses to inflict lasting damage.
Anyway. If fight-move glaives knew to not attack pyros unless numerically superior and in a concave...
