some more context; lets say i'm farming under their tower and they're walking back to lane. prior to them entering tower range i begin autoing them to push them away. why do i take tower aggro?
LostFr0st2 votesYou take aggro because of patch 6.17.
Turrets target champions more consistently.
Turrets are like older brothers. They’re not always around, but when they are, they’ve got your back. They protect their allies... except for the times they don’t. Under normal circumstances, towers focus on opposing champions who damage allies. Due to the way turrets currently acquire targets, however, if their allied champion is too far away, turrets stands idly by while opponents bring the pain, even if those opponents are squarely within firing range. Players have an expectation that towers should protect them, so we’re making sure that they do that.
TURRET BINOCULARS Champions within enemy turret attack range now draw turret aggro when attacking enemy champions within 1400 range of the turret (turret attack range is still unchanged at 775)
NEARSIGHTED TURRET When a turret switches to targeting champions due to having no other units to target, it now prioritizes the closest champion attacking it rather than a random champion in its range
FEEDlNG TIME1 votesThey don't have to be in the turret's range. If you're under an enemy turret and you attack an enemy, you will take aggro.
lightdragoon881 votesBecause **YOU **are in turret range.
Paquay1 votesThey changed the way turrets work. Basically if you are in range and do damage to an enemy champion, the turret will aggro you unless it is already on one of your teammates. This includes things like dots. If you ignite an enemy and they run away, you will get turret aggro if they take a tick of damage.

shroom doesn't make sense?
