Vayne makes you toxic-it's so weird.

I picked up vayne thinking "I'll be different from all those all those other vayne players", then 3 games in I caught myself flaming in chat for the first time in months while watching my replays(I don't have room to think about this during a game), and I don't think it's a coincidence. I quit vayne for a while, and I didn't say much in chat, like usual. Then I played vayne again and the toxicity came back. Is there something about her that draw attention to your teammates? It is so weird and it's actually creeping me out a bit lol.
