Why isn't blitz used in LCS?

Yeah thresh does kinda the same thing except with more utilities but still, blitz has the ability to just feed his adc so freaking hard. If he gets one pull then your basically dead, especially with a good adc. And yes LCS players can just juke him but honestly once he hits level 6 he is tanky enough to just W then run right into them. I personally don't play him because I think he's too easy! At least thresh's hooks take longer to wind up.

Edit: You would think that LCS players would be good enough to not hook the tank though. I mean I understand there are better supports but at the same time It seems like blitz could have a decent impact on the game if played right. Maybe we will see him played in a different meta.
