I don't really get why people wants 6 player party its too crowded considerin how long the combats are as they re with 4 now, u ll need to add more monsters to balance but this will mean gale will surely die in 1st round Jokes aside its not 2nd or 3rd edition anymore you dont need a rogue for traps or lockpick, basically anyclass can handle that, pick the lock with the correct background. You just need to perception check to see traps and shoot an arrow thats it.
You got tons of potions and scrolls dont even need a cleric just rest more..There will be some crafting included possibly in future aswell.
4player party is already too strong for hard diffuculty
you just need 1 tank 1 caster and 2 random classes, ofc in the end of the day we want to play with all the available classes but the playability..so to me
