Think Diablo II where you can hire NPC's to fight with you. There are many times where finding the all elusive WHM to complete your party takes hours! People leave your party before you even get a WHM because it takes so long. THen you have to put up with their arrogance and superior attitude that they are so important and that everyone must listen to them.
So i think it would be a great idea to be able to hire some basic WHM NPC that can auto heal your group in case you can't find a real WHM. What do you think...am I crazy?
