So Zed is broken but Jinx isn't?
Yeah he can assassinate one member of your team, Jinx assassinates your frontline then chases down your squishies with her passive landing 650+ range rockets that two-shot your backline. And she self-peels better then most AD carries by having mobility through her passive, hard CC and soft CC. Her laning phases is ridiculously strong too. Traps and wards keep her safe from ganks, she can bully most AD carries early too.
Not to mention a ridiculous winrate considering her 34% pickrate and occasionally dipping in 56-57% ranges at Plat+
But sure Zed is definitely the problem in this tank meta.
