Not really, I absolutely prefer 6 party members and at least 13 companions like the previous installments if possible (or more XD) but realistically I do not think we are going to have it (They already said so, it´s a Coop MP game with 4 players, etc); so I wanted to point out that if we have only 4 party members in the end that would not be the end of the world because 5e is more flexible than previous installments of D&D.
