I posted this on reddit but I'm posting it here as well:
"So for those of you that don't know, riot had changed the way attack move works a couple patches ago where it automatically targeted the enemy that was closest to your cursor. However, it seems that it has reverted back to the old system where no matter where your cursor is, it just targets the enemy that is nearest to the Champ".
Rox4me1 votesThere is an oprion in game to reverse and enable those two have you maybe clicked it? (It's still extremely stupid to have "disable" as change)
jurajumala11 votesWhat exact option are u talking about?
El Condor Pasa1 votesWorking fine for me.
Make sure you have the attack move on cursor box enabled.
Suzý1 votesAh I see, it's still a bit different though because if you attack move all the way away from all enemies, it will still attack the enemy nearest to the champion. The cursor still needs to be relatively close to the enemy you are trying to click for the game to target it.
Bronze5Season71 votesHi, I have the same problem. Attack move on cursor box is checked, and I have Click Attack Move bounded as Shift + Right Mouse Button.
@ROX4ME : What is the option to "reverse" that you're speaking about ?
