What if Sunfire's passive triggered only upon an AA in the general area within the last 5s or so?
Running past minion waves counts as aggro which disables out-of-combat style effects even if you had no plan to attack/clear them, forcing you to loop around to avoid that.
Running past jungle causes them to chase after you which leads to weird minion-block cases and sometimes giving away where you are/were going.
So what if the Sunfire/Cinder passive only triggers if you autoattacked a unit in the general area within the last 5 seconds or so? And once it triggers, it would last until you exit the range of units affectable by the passive?
