For every lame excuse you nerfed Sona for, it can be applied to most tank supports right now
Oppressive - sure is fun being effortlessly zoned by a Leona in a brush, wanna ward it, well fuck you, get stunned for 3 seconds and take insane damage
Does too well against champs they counter - it's currently suicide to pick a squishy support against a tank support who knows what they are doing
Elbowing out other support options - queue for solo queue, tank support vs tank support, queue again, tank support vs tank support, and again, tank support vs tank support
So much damage - Meanwhile Tahm gets bundles of extra damage just for leveling up his ult, every tank support is loaded with insane amounts of damage with the exception of Alistair, what's the point of supports designed for poke when you can just all in someone with a tank support and take them out at 100% hp?
POPULAR! - LOL Thresh top picked support for 2 years in a row with no signs of stopping being the penultimate support
I hate the bais you have on the support role Riot, anyone not interested in playing tank supports gets shafted, yeah AP and utility supports can be decent, but never allowed to be as good as their tanky favorites.
. That's basically it: the absurd amount of sustain it gives pushes everything else out.
or
I suddenly lost interest and decide not to play the game just because I always remember that I have to face tank supports every matches or remember how I got killed under those helpless turrets when enemy jungler gank...
