Yeah... It's hard to get a party when everyone is screaming for monks and ele's to farm the bosses.

Even so, it's very doable with henchmen alone. I took that screenshot after finishing the first mission inside the furnace, where all those enemies come from different directions and you have to protect that dwarf. It was a bit of a challenge but not that difficult.

So far I've gone all the way to the jungle part with those drench spirit callers. My inventory was full and after seeing a completely red dotted map I decided to return to the camp.
