I fully support this, personally for me I struggled a bit with just 4, I had to really use my brain to win, and I also had to be lucky, a party of 6 would make things a lot more fun, there would be more variety, more epicness having more companions around, more interactions, instead of them waiting on the camp, it would be also be cool to recruit extra people, that we don’t necessarily play with them, but they follow us around until they die or have to go somewhere else, like for me it would be amazing to have a full battle, an epic event, like a war where all the characters were part of.
It would also be better with your playing with friends, imagine being that friend being left out because there is no place for you 😅
