Minions juke harder than most silver/gold players.

I'm wondering why when I play Karthus (just an example) and a minion is within lethal to be last hit with a q, it decides to change target to another minion and move, so I miss, and then it changes target again, and I miss, and then it changes target a third time, and it dies to another minion because it literally jukes better than the enemy laner.

I swear one time a minion juked so hard I tried to lead where it would go but I missed anyway but it hit the enemy laner and I landed comet on them on top of that. Make this not a thing.
