There are a few interactions that Qiyana has with champs from certain regions (Ixtal/Shurima/Piltover) and she says unique voicelines to them despite not being able to see them. This has actually allowed me to locate the enemy jungler while laning with 0 wards down and alerted me to ganks too early.

I don't know if this is just a Qiyana problem or if it happens with other champs too but I never see it spoken about and I think it should definitely be fixed.
