"Underclicking"(Clicking objects under others)
Okay, so, I don't know if this should actually be added because its a strategy to 'abuse' this... but sometimes you just can't click something under something else(Thresh Lantern, Tanks hovering over ADC's, etc.) and it can completely change the tide of a battle, or even ambush.
So, I was wondering... what about a hotkey? You could press it, and it would elevate the next object being covered by the top object, and so on until you get to the thing you want.
So, say you're stuck in a corner in the jungle, or anywhere. Your Thresh throws a lantern, and you try to click it, but your enemies get to it first and stand on it so that you can't get to it. What do you do? They've made it impossible to get away unless you have flash or some kind of ability dash.
Another example: You're in a teamfight. Tanks go in first, obviously, and the squishies come in and stand UNDER them. You can't even attack them, and they're melting your health pool because you can't do anything. Wam, you've lost that teamfight.
So, how do you fix that? Thresh Lantern: Press said hotkey until you can click the lantern, click it, and take off over the wall. That little button just saved your life. Teamfight: Press said hotkey until you can click whoever you're aiming for, and start trading damage back.
