Picked "still not convinced" but my true feeling is probably between that and looking good- cautiously optimistic would be the word. To get the bad out of way, I'm very much not convinced that Covenants will be a success mechanics-wise when too much is tied to such an irreversible choice, in a game where players have had min-maxing beaten into them for 15 years by both Blizzard and the community. I'm also not sold on the premise of the main story, I just hope the plot isn't some Sylvanas wank-fest about how life is pain and all that morally grey jazz, and they shouldn't fuck too much with Scourge lore as well.
But I like covenants as a story and role-playing tool, I like the class changes as a whole, I like Torghast, I like the high fantasy vibe, I actually like that they're trying to do more with returning characters like Kael and Ysera, I like what we've seen of the reward structure thus far, I like the new racial customizations, and my word do some of these transmogs look cool as fuck.
Blizzard have also been unusually responsive to feedback during the Alpha; the Torments change being only the latest example of them listening to feedback. This gives me hope that their design process has changed to be more flexible and able to switch direction more quickly. If nothing else I'm much more optimistic about it than I was for BFA.
