How do you deal with Illithids?

Maybe a bunch of crappy Tribal Archers and Warriors would be the more cheap effective way of dealing with them ?
I'm not that fond either of pure Templars/Knights armies :they are often just overpowered by a swarm of cheaper troops, easily peltered with spells, etc... They should be use IMO as a elite offensive force, and be supported by infantry. Pikeneers, flail-armed infantry, crossbowmen, and some Hvy Inf mercs are good for that.

Yep.

Tribals are the some of the best, fastest-recruited cannon fodder I've seen.
