Sett does not need base stat nerfs
He is a champion that relies on base defensive stats. I don’t think it’s wise to hurt this area, because then you allow the ridiculous aspects of his kit to flourish when that shouldn’t be the case - although I do think a base regen nerf is in order, but not base armor. I think a very simple fix would be to reduce the stun duration on his E. In melee match-ups in particular, this spell is incredibly punishing. It’s easy as hell for him to land it, and he gets a 1 second stun upon doing so. I’d argue it shouldn’t stun at all, since he already has tools to stick to targets with his Q and R, not to mention his E still slows. The problem you get here is that when he stuns you, he has 1 full second to beat up on you without you being able to retaliate. He doesn’t even need to get low on HP so be threatening here, the damage on his Q and passive is damaging enough.
So I would propose a few ideas here:
Remove the stun entirely, and give it the talon treatment: a 99% slow for 1 second. He can still stay on top of you here, but you can at least cast spells to fight back. This does hurt his teamfight though, but I think it’s probably the best of all worlds.
Allow the stun to remain, but make it much harder to land by slowing the launching speed of his E or reducing the hit box. This is funky to me, because it really wouldnt change much in melee match ups, while dicking him more in ranged match ups.
Nerf the duration of the stun at early levels, and also increase the early level cooldowns so he’s not so punishing in lane.
I really think Riot should reconsider their base stat nerfs. I wouldn’t even be against removing all the current nerfs if they really take away the power of his E. His W is unique and quite frankly, fucking cool. Even his Q and passive feel incredibly unique. For this, base stats really matter to both his W and Q because he depends on regen and durability to maximize their effectiveness. That’s not what really makes him busted though, it’s the fact that it’s easy for him to stun his targets and they can’t really fight back. That’s the real problem.
