teach that to riot then, until then i don't care about kr
That's your problem. Chances are that the top players from the strongest region will know what's particularly strong.

pro scene is not solo queue, and pro scene didn't play on 7.15 where thresh has been massively nerfed
While patches are generally targeted around soloQ, with the exceptions of:
Thresh was overperforming in solo queue and that was clear ever since midseason patch. His winrate spiked like number 2 or 3 IIRC.
And I don't call the bugfix a nerf. In reality, yes, it was a nerf, but it was a removal of an interaction that shouldn't have existed in the first place.
This is from the tooltip (from Thresh's league wiki page:
Flay
ACTIVE: Thresh sweeps his chain in a broad line towards the target direction, dealing magic damage to enemies hit, knocking them in the chain's direction, and slowing them afterwards for 1 second.
Show me where one word about stunning Flayed targets for a brief moment after displacing them. If you tell me it doesn't exist, that interaction was bullshit to begin with and shouldn't have been there at all.

he has as much utility as any other support
if a support has less utility than him, then they have more damage which makes it balanced
Let's list his abilities:
Q - hook, same range as Nautilus, higher than Blitzcrank; is non-commital compared to the other 2, stuns for 1,5s, reduces cooldown by 3s on-hit (ANYTHING), trajectory is hard-to read because of the animation, janky hitbox as well.
W - gives vision, picks up souls lying around it, gives a shield with infinite scaling, pick-up range is twice as big as deploy range.
E - gives AA bonus damage when charged, provides a lockdown from your hook engage/disengage, slows targets hit
R - lockdown/disengage, brutally slows first champion, deals quite a lot of damage actually
Tell me what champion has as much utility as him and does even comparable damage. Name me like 2 or 3 champions that do nearly enough things as Thresh does.
