1. Party Customization : BG3 should have a customizable companion system or allow for stats customization by the player.
Game devs are not necessarily good at games, that is, in this case if companions come with preset stats and feats, they might not be optimized or even make sense for their class. A good example is Pillars of Eternity, a fantastic game but it does suffer from the aforementioned issue.
Some companions in PoE have poorly allocated stats, which leads to an incentive to not have them on your party. It doesn't matter how well written a companion is, if he/she becomes a nuissance when in combat.
This leads to the next suggestion.
The option to create all 6 party members should also be an option, for those who like to play Baldurs Gate that way.
