OMG DO YOU KNOW WHAT YOU HAVE DONE RIOT!
You have destroyed Blitzcrank. This retarded slow on his overdrive is the dumbest move ever. Now it cannot even be used to get away because even with boots and move speed bonuses, he is still below 400ms. Not to mention, you pop overdrive and 5 seconds later you are slowed down to 250ms. Hello all the enemies I was running from, nice to see you again. This is the dumbest ability in the entirety of LoL. It serves no purpose anymore. Sure you get some attack speed but blitz is more of a support champ and this is how he is always played.
In conclusion, thanks for killing Blitz.
Peace
