1) A robot support may not injure a human being their carry or, through inaction, allow a human being their carry to come to harm.

2) A robot support must obey the orders given to it by human beings its carry, except where such orders would conflict with the First Law (i.e., don't set up a kill that might be risky for your carry).

3) A robot support must protect its own existence as long as such protection does not conflict with the First or Second Law.

==========================

Rule #1: You are a support. You are your carry's *****.
Rule #2: Your carry is a dumbass. Let him focus on poking minions while you keep track of the entire map.
Rule #3: Your carry is a still dumbass. You need to tell him what to do. Ping him to follow up your target or to fall back while you peel.
Rule #4: If you can engage on a fight to distract the enemy from killing an ally, do so. If neither of you will survive if you try to go in, don't try. Your gp10 means your death is less of a loss of personal gold and less of a gain of gold to the enemy that your carry or mage's death.
Rule #5: Your carry can't get EVERY kill. This includes CS. If your carry is not in a proper position to take a kill, take it.
Rule #6: Your jungler can't be everywhere, especially if he's dead. Place a Vision Ward in your own tribush and in river so your jungler knows where the enemy has vision or to deny the enemy vision.
