You aren't making any relevant arguments, and are contradicting yourself a bit making this confusing:
His statistics were to prove that even higher elos don't "shut down" Blitz. The entire point of showing his winrate being constant across elos was to show that it isn't a matter of it being difficult to fight blitz, but that blitz's reliance on a single ability creates a cancerous environment and a constant success rate
He wasn't complaining about Blitz being OP as you seemed to think here:
51% win rate shows that he is very balanced. Pretty much exactly what a league champion should have. Same thing with games played.
(hell, win rate =/= balanced either. When Zed was running rampant he had a 52% winrate because teams were forced to counterpick him...much like teams do against Blitz through
or any champ with a blink/dash)
and when you said
Any champion with a pick ability can make sure you are dead.
The only champion with a pick ability even close to Blitz's is Naut's which has serious setbacks such as not being able to travel through terrain and how it meets you half way. Blitz's pull is easily the best pick ability in the game and that's what we are discussing, not the other pick abilities that aren't even the same as Blitz's.
You haven't actually stated anything relevant to his argument really. You may think Blitzcrank's kit is a fun and fair situation, and that's completely your right to have that opinion. But in our opinion, having a kit that forces you to avoid him or die through all of lane phase (by nit picking every step and having to track minion movements + maintain bush control) and has the harshest punishment for mistakes as well as a consistent success rate seems pretty toxic and anti-fun to me.
Now you can keep downvoting every comment that disagrees with you in this thread, but at least understand our argument instead of making up your own
