I understand the sentiments. There definitely has to be something about Starlight that made her over-react like this. I don’t want to get too heavy into thinking she has some mental disorder as discussions like that can turn sour pretty quickly and could lead to generalizing people that have said problems and I don’t like doing that. But it’s clear Starlight has issues.

One thing that just has to be covered in Season 6 is Starlight reuniting with her friend Sunburst. We need to know why he couldn’t have just visited or sent letters to Starlight to reassure her. If he literally has no reason, then at least Starlight feels more like a victim in that her friend really did abandon her after getting his cutie mark. Though at the same time that makes Sunburst look like the big jerk now for never contacting his friend just because he got his Cutie Mark and was sent to the Magic school in Canterlot.

Like I said the way they did this is similar to if they had Sunset join the main show as a recurring character after the first Equestria Girls movie. We saw her being a bitch throughout most of the first movie, and then get pretty quickly reformed. If they had Sunset join the Main show as a recurring character after that, there’d be similar feelings regarding Starlight now. Just replace the time shenanigans & village manipulating with turning into a demon and trying to take over Equestria with mind-controlled teenagers. Now thanks to Rainbow Rocks and Friendship Games, people would love to see Sunset back in Equestria some day. So I imagine they’ll attempt to have that sort of thing for Starlight in-show. Assuming Equestria Girls never affects the show hugely, Starlight is pretty much this show’s Sunset even if course due to not having Sunset’s development in the last 2 EQG movies won’t be as popular. And depending how they portray her in Season 6 may or may not be as well-liked as Sunset’s turn-around that started with Rainbow Rocks. It probably doesn’t help that their last name’s rhyme and they’re both former foils for Twilight. So they kinda feel like carbon copies of one another.
