I would also like to be able to create my own party of 4 characters.
I like min/max my characters and build them as I want.
I am very disturbed by the attributes of the companions currently like Shadowheart. And I can't even make Lae'zel a tank with shield because she has the perk to increase her damage on longsword.
I would like to be able to recruit 3 mercenaries from the start of the game as if they were in vats in the tutorial.
In DOS2 you had to wait for the end of act 1 and I didn't like it.
