Been playing DOS 2, and I got to mercenaries lizard lady. I got excited. Maybe I could create a second custom character.

Nope. You just tell the lizard lady you want a fighter or rogue or whatever and she gives you a prebuilt character. No custom character for me.

I ABSOLUTELY do not want that for BG3. I want to be able to create custom companions from scratch like I do my MC. I'd like the option to create up to 4 custom characters in the beginning and an option to create additional custom characters at the Grove and switch out ones that die and/or that just aren't working.

Maybe Aradin had more mercenaries as part of his team, but they rejected his leadership later and decided to remain at the grove. Maybe you can recruit them via someone like Zevlor or the tiefling training the kids.

Just PLEASE let us create our own and recruit and dismiss companions as we see fit.

Finally, another plug for party of 6. I wanted 1 or 2 custom characters in DOS WITH Lohse and Beast and Ifan. That would have been SO cool. The same is true for BG3. 4 custom characters plus 2 origin would allow so much flexibility and I'd be able to still enjoy origin characters stories.
