That rating system is all but obsolete now. It doesn't take into account online streaming views. Looking at other Disney XD shows, the rating is fairly consistent. Mickey Mouse, of course, gets the highest ratings.
Just because it's high for Disney XD doesn't mean it's high in general.
TCW at it's lowest in it's 5th season would still get like 1.4 million viewers. It was on a higher watched channel, but what does that matter when talking about how many people watch Rebels or even know it exists?
Given that would be a very bad idea to explain the back story of a Star Wars movie villain in this animation. Unless it's just "extra" background info that's interesting but not essential to know.
Snoke was considered to be designed as a woman.
Clone Wars is canon.
I like the idea to think that maybe Snoke is Ventress. Badly injured, Her skin scorched, her voice brutally broken by throat damages...
For the Empire, against the rebel alliance.
"Good" is a point of view...The Sith and the Jedi are similar in almost every way.
