Don't know about Paladins getting a battle rezz. They are already a healer that everybody wants to have and that has a lot of utility. What about Monks, maybe for once? The class is mostly useless and is never considered a mandatory part of a raid. Same goes for Evoker getting Heroism / Bloodlust, why? Evoker has already TONS of utility, they really don't need this.
Dragonflight launching end of November sounds plausible now and it's... okay? I like November releases, it feels more natural than the August expansion launches for Legion and BfA.
