Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Suggestions and Feedback More than 4 character to control

I am wondering if 4 characters is a bit too little to accommodate all the skill trees.
most of the time my party is:
1 mage air/hydro
1 mage fire/earth/necro
1 Ranger/scoundrel
1 warrior


I am wondering where on earth I would put the summoning master skill tree and the polymorph skill tree.

I think that with 4 characters to control we will have to choose what skill tree we ignore (or a lonely point in the tree).

I would suggest that if it is possible to bump the party size to 6. This would mean a huge overhaul of the combat difficulty and the inventory management would become even more strenuous. But at least you would be able to use all the skill to their full potential?
