Talon Silence
Well, with the recent nerf on Talon, he lost his silence and instead gains a 99% slow. It isn't a bad nerf, because Talon could silence his enemies and amplify the damage done to them while whoever he was attacking couldn't respond, so considering that it was a decent nerf.
On the other side, without the silence, Talon can't use the silence defensively either, looking at a common matchup, Talon vs. Katarina, Talon can no longer use his silence defensively to stop her channel [at the least I haven't seen anything that says his e breaks channels].
Lets observe another champion for a brief moment who also had a silence that was almost as abusive as Talon's, Kassadin. Kassadin now had a change to his q where it doesn't silence his enemies, but what is surprising is that it says right on the tooltip that it stop channeled spells. Sure he no longer has a silence, balancing his q a little bit, but at the same time, he can still use his q defensively to break an offensive channel [malz ult, kat ult, Warwick ult etc.] Now, going back to Talon, I think it would be fair if either:
A: Talon can silence only when he's stealthed meaning that he can only silence when he's ulting, giving his all in a little bit more power as it used to
Or alternatively
B: Talon's e breaks channels, but cannot silence any other way.
