Talon's fine, he has some counterplay in terms of his kit, the rest I agree on.
kaisa, ryze and azir are just too good
Damage is so high in general currently that Rengar can actually 1 shot adcs with a single auto. Talon was okay until damage became so high because he'd usually have to do a perfect Flower combo to kill very quickly. He doesn't need to now damage is so high between elec, sudden impact, everyone losing armour in runes, duskblade, etc. I hope the rune changes next year make it so he can't do what he's doing right now, despite myself being a beneficiary of it, I would still like Talon to need to full combo properly to kill like he needed to last year.
However, he does need to be reasonably fed to one shot with no counterplay, I noticed you have Ahri in your name, you can actually E him out of his Q and deny the damage + passive stack, I don't know if you knew this and I have no idea if it's intended or a bug (as Ahri E isn't meant to interrupt dashes) but I can confirm it works.
