Im honestly sick and tired of this topic. Saying that the previous titles had it and therefor this one should have it is disengenous. All those games pretty much came out roughly the same time. If your competition has a popular setup it makes sense to 'borrow' the idea.

Dnd itself isent balanced around 6 man parties and saying that upping the party size by 50% brings no balance issues to the table makes you look like you dont know what you are talking about.

Encounter difficulty sits on a very narrow balance. They shouldnt be to easy nor to hard. Adding 50% more fighters to 1 side and not giving the other side something completly throws that balance out of the window.

That said its complained about so much by people that maybe they should add a '6 man party' option to the game and just say thats its balanced around 4 man parties. That way people can still have it and if people want the intended challenge of the game those peoplecan also stil have that.
