Sorry you feel this way but if that’s what you were hoping for then it sounds like Classic isn’t really for you. That’s okay though. I still encourage you to try it though!
It’s not throwing it away, its giving the community that wants Classic the most authentic experience we can provide. Adding any sort of reward carry over in either direction isn’t authentic and defeats the point.
Classic is there for those that will want to play it. Not just for rewards on their BfA license, which would be devaluing to those that earned those rewards that are no longer obtainable, and vice versa would be introducing things that were never there in Classic to begin with. Neither of which we want to do in this case. We know the community that has been asking for Classic for years doesn’t want either of those scenarios, and neither do we.
