So I can put a fuller post with a more detailed explanation later but with exception of T3. Which is weird for icon assignment. But in general:
Units with Bot Assignment Strategic Icon. Had/Have higher DPS and with 1 Non T3 Exception Higher Movement than “Directfire” Equivalents.
All Labs had Higher DPS than tanks.
All T2 DirectBots had higher DPS than Tanks.
BotAntiAir had Higher DPS than TankAntiAir.
All Bots in general have had Higher Movement Speed Than TankDirectFire. Bots had lower HP than Tank Equivalent except for Aurora. Now Mantis, is also Bot Icon for Intel reasons as stated.
Now interesting Ilshavoh is only T2 Bot Icon that an exception to this rule (and is noted in BP as having the wrong icon).
That said I would prefer Aurico solution, because it keeps the intel situation sense the similar icon results in a momentary confusion for players. But it keeps it distinctive removes the bad feels.
Also I would argue for introduction for whole host of new strategic icons to be frank. Like if I could I’d introduce the following new icons (bias exists here I’ll admit:
Air Engineer Icon (For Drones)
QGateway Factory Icon
Amphibious/Hover Icon for DirectFire/Scout/Missile/AntiAir/Arty
Bot/Land T2 Sniper Icon
