Talon needs an ACTUAL nerf. Removing his silence for a slow only increased his damage output.
I don't know the mastery changes for S5, but the extra % damage you put in really gave his already innate 3-15% damage increase a huge buff.
You get a total of 16% from masteries, one of which requires you to have your target below 50% health. So lets say 13%. Combined with his E, you get 19-28% extra damage on your spells. THEN you add in his extra 10% from his passive, you get 29-38% extra damage on your basic attacks. That's an absurdly large amount of extra damage for basically doing nothing. He already has 2 slows, the silence never proc'd off his passive. But with that change, you actually get more damage off when you E/Q/W/AA/ or whatever combo you choose to use.
Why should talon get ANY free damage increase from his spells when he has a reveal, gap-closer, 350 (350 on a champ with a fucking auto target blink???) movement speed, stealth, an AA reset in his Q, AND low cool downs.
No. Talon is not a fun champion to play against as anyone because all you have to do is rush Brut and LW and you pretty much 100-0 anyone who doesn't have 3k health. Talon is not a fun champion to play against, especially in 3's (And you've already nerfed other champions for that mode, i.e. Cass, Teemo, Sona) in the past. So he needs to be gutted if you don't remove the free % from masteries.
Talon needs to be reworked or nerfed because getting all that free damage combined with being an Assassin/Burst/AD user, is just crazy nonsensical.
