Blitzcrank Pulls ...

I main Blitzcrank ... ( i know im bad so all you toxic players be quiet ) but I' ve been noticing that his pulls would go through enemies more often instead of pulling them . I have been playing Blitzcrank for a while and I know it would happen some times but now its happening way too much. Also when you try to pull a enemy champion who is like near a minion your pull will shift towards the minion instead but that's just a minor problem, because if your grab touches the champion it seems like its a 75% chance that you will grab him. I usually play with my friends and I always ask them if they seen my grab touch the enemy champs they would always reply '' yeah how did it not pull him tho '' . Did anyone else counter this bug plz let me know in the comment section below thnx
