I would like to see that you could have up to 3 hirelings and being able to swap them in and out just like every other character.
As it stands, it seems like if you dismiss them you lose access to them and have to rehire them again next time you want them. Well, I havent actually tried doing so, but I read its like that in this forum.
That makes hirelings basically uninteresting to me, since I swap around my party all the time and wanted hirelings to fill the gaps. Having to constantly level them up again whenever I rehire them is too much of a PITA to bother.
