BG3 is already expected to allow 4 customs, at least for multiplayer. And hasn't it already been shown that Lae'zel and Us join your tutorial party with no problem??
If GM4Him is arguing for the option of playing with 4 customs + 2 Origins, but you can still play with 1 custom + 5 origins, then that's fine. (I assume this is what you mean?)
If he's arguing for that being the only way you can have a party of 6 is that you have 4 customs, then no, hard disagree.
Option. Not forced.
Currently even with the mod, you can't play 4 player with even a single origin. You can do 3 players with 6 via the mod, but not 4.
I'm trying to say I want them to allow party of 6 and balance 5e with party of 6 as a difficulty setting. Keep party of 4 as an option for the nerfed EA difficulty setting. What I don't want is a 5e difficulty that is super hard because they limit us to party of 4 and balance everything for party of 4 but then unnerf monsters for 5e difficulty.
In other words, they throw 3 intellect devourers at us with nerfed gameplay and stats but then keep 3 intellect devourers and implement 5e and expect 2 level 1 characters to beat 3 intellect devourers with resistance and devour intellect. Let me at least have the option to create a decent party of I want so 3 intellect devourers won't wipe the floor with me. If you want to go at it with 2, that's up to you, but let me have the option to have more.
