Targeting issues.

ok so i suck right I'm sure imma hear a ton of "get god" reply, but here is my one and only issue i keep having, this is minions how can the games targeting system target a minion over a champ? i have countless times died because i hit a minion and not the player and this is because the players and minion are basically on top of each other and in some cases the champ ever completely covers the minion for example sion i have on many occasions hit talons Q to leap in and it hit a minion i couldn't even see until sion moved away or like annie when you use your Q to stun someone and it hits the minion at their feet.......is there a way to fix this at all, is it a setting that i can change or is it just a part of the game that will never be fixed?
