Why - I'd like to have a Seldarine Drow follower but I cant see any of the existing characters as such.
Obviously one could switch Human/Half-Elf/Elf around with little problem. Shadowheart as High Elf for example. Astarion as Human. Etc.
Astarion I'd like as Halfling.
Gale as Gnome.
Wyll as Seldarine Drow, but it makes no sense whatsoever with the backstory.
Those are powergamer choices though.
