Companions are going to lack in diversity based on the direction Larian is going. We have 12 classes and 9 races in the PHB. Larian seems to be going in the direction of 8 companions, based on what I've heard (though I hope I am wrong). Of those 8, we have 2 humans, 1 half-elf, 1 elf, and 1 githyanki. In my opinion, there should either be 1 companion for every race, or 1 companion for every class, so we have good customization of party without sacrificing major options for no good reason.
