My Purchased Mount In Retail

Why can we not have our mounts and pets in Wow Classic that we have already purchased in Wow retail? Also could you make it to where we can Transfer a character from Retail to Classic.

class and retail are completely separate in the spirit of a immersive classic experience … next you would want flying …

these posts should be contained in the wow classic forums posting here is for the blizzard api nothing to do with anything in game
