Right now it's impossible to determine what the outcome of different choices will be. Common sense says that Sylvanas will be deposed and the people who sided with her will get a traitor's death, but Afriasbi keeps insisting that this won't be a "SoO v2" and Sylvanas won't "end up in chains".
Some of us have invested 14 years into our characters. Making the "wrong" decisions and being reprimanded by the "winning side" for the rest of our WoW careers would be less than satisfying.
There needs to be more transparency about what these player choice quests will result in. The following information is absolutely necessary:
(1) Will player choices have long-lasting effects beyond BfA?
(2) What will be the reward for siding with Saurfang?
(3) What will be the reward for siding with Sylvanas?
(4) Which side is the "right" one?
