Larian have clearly designed the whole game around having a party size of four. I really can't see them ripping out all their planning and encounters to rebalance for a different size. Who knows, maybe they will? I think it highly unlikely, however, that a company already on a deadline and with so much already developed, will decide to go down that route. I don't think that either selfish or stupid, I think it realistic.
You obviously believe that you have the influence to get those sort of fundamental changes made by Larian. I'm not saying you are definitely wrong. I am saying that I would be very surprised if you are right.
Oh sorry, I forgot that anything was balanced actually.
Don't change anything and let us play with 5 companions, it would be better, and still unbalanced... Maybe even less than now.
