What if the portals were little stone mountains (just tryna stick to the "nature" theme)

Me neither....that is the work of the skills: "Mycology" and "Farming."

I think there is a skill point that allows you to make your minions stay in one set place

So...if you are at the waterfall meadow, you gain points/per second?

Although I like this idea, I can't help but think. What if someone changes their class to all swords in the middle of a battle? In my opinion that would be kinda op. Same thing with everything else: all axes to cut down trees, all archers for killing rabbits, etc.
