Well, mercenaries do seem to have a quite significant initial recruit cost, a lump sum you need to pay to get them. So holding on to them is, relatively, cheaper than getting them. Which should provide an incentive to preserve them, at least for the duration of the current war.
The reason why mercenaries charge such exorbitant rates, and the reason why they should do so, is that you only hire them when you actually need to fight. Unlike a regular army that you hire and pay for even when there's no fighting to be done. So as long as they are appropriately costly, I don't see any problem with them seeing rough and frequent use.
