Yeah, the goblin's exp levels are terrible. I'm on level 40 and getting plans and stuff for level 50+ gear, and I cant fight past this blue haired boss at all. He kills like 3 of my guys in one shot, turns invisible then kills the last guy. It went from really fun to incredibly frustrating. Limiting crafting and what your monsters can wear by level doesnt seem to add anything at all. The cost of skill resets is ridiculous too. It just keeps increasing the higher in level you are. I was really having fun with this as a low-pressure version of Shop Heroes though.
