Why does Aglaea get much hate?

Really don’t understand why she gets so much disdain, it’s the same with Rappa too. Anytime I make a post about how they did well for me in content in anything besides their respective subreddit, there’s just people spouting hate. Like I 0 cycled and 8000 PF with my Aglaea team and was excited to have her finally and show her results, and i get comments of “Therta can do that with a F2P team” or “waste of money.” I can’t talk about any characters I like without Therta being brought up as better, like what is going on?? It just discourages me from bothering from engaging in the community…

Like I get if you think she’s bad or not to your taste, but what happened to preaching “enjoy the game how you like and pulling the characters you want?”
