Slingers are useful against trrops with glamour, just like markatas are.

You don't care (so much) about glamour. You want a cheap and effective way to get rid of glamour - and a hit - any hit will do it.

You want to divide your resource allocation between cheap troops that can dispell the glamour - and reasonably troops that can, one the glamour is gone, kill them.

All at a cost equal or less than the unit cost for vanheim's/tir's troops.
