Actually Suramar quest rewards start at 810 (higher than normal) and go up to 825 (5man heroic) for later quests so no complaints there.
Childish tantrum aside, my main annoyance is that it blocks your class campaign progress as you need Court of stars.
Also grinding white mobs for mana takes no effort whatsoever, just time. Hell you can go to some areas with super fast respawn and just throw dots around while friendly NPCs/other players kill everything. Such effort. Boring as fuck but efficient.
