Targeted Abilities / Auto Attacks and League Pathing

My two biggest pet peeves about this game are the way targeted abilities work, and the pathing in game. One specific example i will give is if someone jumps away with a dash or Flash while the enemy uses a targeted ability, the ability will still go off even if the champion is WAY out of range. (i.e. Irelia's E on Gnar after he jumps, flash away from Cho'gath ult or Garen Ult, but they still kill you even if you are a mile away). These abilities should simply not go off if the champion goes out of the cast range. It makes no sense, is extremely frustrating to play against, and does not add enjoyment for the person using the targeted ability. My other major problem with the game is pathing and minion blocking. For example, when i want to use an dash over a wall, I have to click right in front of the wall instead of where I want to go. Or, the pathing will take me on a route that i did not want simply because it is a slightly shorter distance. Pathing should move you in the direction of where you click, not via the most efficient route to get there. Minion blocking is also extremely annoying. There have been countless times when I'm running away from an enemy and i have to walk through my own minion wave, only to find that my minions want to offer me as a blood sacrifice. It is simply ridiculous that your own minions are able to kill you, but is slightly more understandable if the enemy minions do it. Your own minions should not be able to prevent you from moving, and this feature should be entirely removed from the game.

And it's not just me who thinks this stuff; all of my friends who play league have similar complaints, so don't label me as a whiny noob.
