"The larger the group the more pointless each member becomes." Neither logical nor true.
"You are basically asking for the game to be Warhammer and the "party" being an army." Nobody has asked for this, and six is lightyears away from being an "army." Ridiculous.
"... battles is not the main objective of BG3. Most of the battles has a way to entirely avoid them ...." From everything I've seen in the EA portion of the game, battles *are* the main objective in the game. And battles being avoidable is mostly a farce because the game clearly incentivizes the combat option over any and all other options.
"... what are you going to do with those 10 party members?" How did six become ten? Again, who here has asked for ten?
So, exaggerations, strawmen, and false claims all over the place.
