Is there a reason to switch out mercs?
I just got Jagged Alliance 3 in the Steam Sales, and I have renewed the contracts of my mercs twice now, pretty good on money so far so I tried hiring "Buns" but she won't work with me because "Fox" is on my team, so I got thinking about how changing mercs works (with their invtory and stuff) and if it is even worth to change them since they get better with time.
So any veterans with some advice would he greatly appreciated.
