Where do you think this "Player choice" stuff will lead?

I'm referring to the Horde Sylvanas questlines where you can choose to side with Saurfang or Sylvanas.

I really can't see where it will eventually lead. If Sylvanas is going to end up as a raid boss, then will they split it so that people who sided with her get a different boss? Just not sure how that would work. But if people that sided with Sylvanas end up having to fight her anyway, they will be livid and the whole thing will have been pointless.

Not to mention that it currently doesn't actually change much. Looking at the 8.2 quest line, every time you side with Sylvanas it just becomes a "Play along for now..." situation where you still do the same thing anyway. You can play along forever but eventually there has to actually be some crossroads.

What do you think?

Edit: Genuine question, why is this getting downvoted? Is this not a valid topic of discussion?
