Well, that's a little too early to say much about it really. From what little info they gave, calling it a "massive directional change"doesn't really match what was said, I'd be careful calling it even "minor" tbh. Most of the abilities they presented change about nothing gameplay wise. Nothing.
Besides, I won't believe until I see it.
This really.
PS: Considering how big of an issue class design became in Legion/BfA for a LOT of people, its more than worrying that they didn't have much/anything too say about their plans regarding this topic. Like... adding a few almost meaningless abilities and calling it a day just won't do,
