Senna is unhealthy for the game change my mind

Let me just check her winrate... aaaaand yep, you're just bad.

skill issue

Senna is one of the lowest win rate supports right now.

Why don’t you try playing her yourself? Either you’ll discover how to counter her, or you’ll become challenger since she’s so broken.

Ok I'm bronze but even I can see a skill issue when it's being waved in my face

win earlier

If you're trash it's easy to get owned by a half-decent Senna. Probably what happened.

Post your opgg if you want a real discussion. Otherwise go cry in your bedroom.

Hmm funny how none of your arguments are actually good :

Infinite scaling : so veigar, smolder, nasus, swain are unhealthy ?

3 shot combo : not worse than assassins, and she only delete you if really fed and you have 0 armor, plus you can delete her as fast.

Slow hard : well 15% early, seems not high compared to a lot of slows. It scales decently but far from being horrible.

Stealth : hmm you know you can just get closer to her and she will no longer be stealth ?

To summarize : get good.

Your delusional. Senna isn't 3 shoting anyone unless she is giga fed or against some uber squishy super late game.
