EQG was always the neglected stepchild of the IP. Bad concept, bad execution at times, and not nearly enough resources to ever make it a worthwhile endeavor. It makes sense it would clumsily skid to a halt this way.
That being said, it was still charming, the music was unreal, and some of the writing was top notch. Not to mention we got Sunset Shimmer out of it, who started off this obnoxious, one dimensional character, and transformed into an endearing, wonderful, and deep protagonist. For Sunset alone, it was worth it.
RIP, EQG. I’ll go to my grave listening to Welcome to the Show, Shine Like Rainbows, Right There In Front of Me, Dance Magic, and my favorite MLP song of all, Hope Shines Eternal.
