Some questions about kindred's abilities

I don't know if I'm on the right forums or if I need to be on PBE boards specifically or something, but regarding her damage and stuff, is there a particular reason her Q doesn't prioritize champions? I use my Q to try and finish off champions but all 3 arrows go into minions behind or beside me, I feel like if you played with her damage ratios on her w / third E proc, it would be more reasonable for at least the first arrow to focus a champion. It might've been a glitch but it's just what I've noticed feels off about her so far, if she's supposed to be viable for adc as well, I feel like the Q should focus champions.
