Due to the range problem, I've given up using slingers as a field combat unit. I do recall recruiting them once as Arco in a particular game that favored the use of Flaming Arrows. Used them there as fort garrisons, since they had cheap strength/cost ratios and the wall of the fort would prevent them from running headlong into the enemy. They would just mob up against it for a while until the enemy got close enough and then pelt them like they were supposed to. It was ok.

My other (rare) use of slingers is as archer decoys. Since they are technically "archers" you can use them to absorb anything that would normally target your worthwhile missle units.

Edit: On a side note.. you know what might be a fun unit? Some kind of Seige Engine type thing. Size 6, 1 strat move, 0 tac move, 0/0 att/def, 50 hp maybe, some prot perhaps? maybe a kite shield for equipment to make it hard to kill with arrows. And all it would do is cast Flying Shards or something with range 15-20. So - not useful in the field due to the short range. But if you put it as far forward as possible during a siege it would be able to fire at the attackers/defenders over the wall.
