Then Mercs must be made into something that doesn't piss your money away.
Unless they start respawning or their price drops that won't happen.
I'm at least optimistic they'll be given some attention now. If they do get improved in some way, though, I'd suggest that mercs and slaves on guard duty also count towards a person's limit (I have no idea why they don't).

The should be, its a bug that either is fixed and not update4d yet, or will be fixed. Also, prices are dynamic, so they should settle at reasonable prices over time.
you mean that mercs on guard should count toward charisma limit?
