Morgana's ban rate
According to https://u.gg/lol/tier-list?rank=platinum&role=support
She has an unfavorable win rate against pretty much every single support. She's sub 50% win rate overall. Yet she has an extremely high ban rate. Why?
I understood this a few patches ago when a dive comp was common bot lane, but now that bot lane has returned to normal it seems confusing she's still banned. Rakan's popularity has plummeted due to recent nerfs. He was pretty hard countered by her.
What exactly is she countering right now?
Also please don't say something like "lulz undodgable 3 second snare and immunity to CC". It has a lot of counter play if you're not silver/bronze.
It seems to me that as far as supports go Nami should be pick or ban every time right now. Am I wrong?
