Why don't people ever use Juhani in JKR squads?

I tried her for jkr mirrors ages ago when jkr was my arena team (didn't have hoda so I was experimenting). And found her to be useless, dies pretty quick, taunt gets dispelled so I found using ezra was more beneficial and even old ben worked better. She fits in nicely with Jkr's lead but she's not a great toon in general. If you have no other choices then go for it but there are better toons for that final spot and you can experiment for yourself to check if you like
