My post post got glossed over in the back pretty quickly.
But I had mentioned my feedback on why the game should not be 6 players since its not balanced for that as per dnd 5e ruleset
The game of Dungeons & Dragons Fifth Edition and its encounters is balanced on two basic premises.
Each adventuring day, a party of three to five adventurers should be able to handle six to eight Medium or Hard encounters (DMG, page 84). Most combat encounters should last 3 rounds on average (DMG, page 274). This means that the characters playing the game should have enough resources–including hit points, spells, special powers, etc.–to last roughly 18 rounds of combat. In addition, the party should take at least two short rests per day to recover a portion of their spent resources.
So basically Larian has took the average of what the balance is currently made for. Its NEVER 6 players if you do that you actually have to make the game HARDER by changing the CR by tweaking numbers all across the board on top of much higher DCs for everything.
But the argument for having a 5th i could easily see since it normally is per CR in the monster manual on top of the current Environmental effects causing a lot more damage (( they need to remove this ))than you would find an in actual dnd tabletop setting.
Remove all the extra unneeded environmental damage that isnt a thing in 5e, Remove the healing on food, Put back that number of value on healing into potions of Healing Add more short rests
By doing these things a party of 4 or 5 should be fine.
