gonna chime in a bit on subclasses myself.
In addition to the Core subclasses from the PHB, I strongly think given that this is BAULDER'S GATE the subclasses from the players guide to the sword coast needs to be included. the bladedancer, the purple dragon knight etc.
Good point! Some of that (like the Bladedancer) will be updated in Tasha's Cauldron. Hope they update the Purple Dragon Knight sometime - that subclass needs a little love.
