Minion behavior

Being able to CS obviously important, as it not only gives you gold but let's you stay at the same level as the enemy laner. I'm by no means an expert, but after playing this game several years I've learned a few things that might help you. I've noticed that once an enemy minion's health get's below a certain amount (I don't know the exact amount, but it's pretty low), your own minions will start to aggro it (even if they were attacking something else). This usually happens after you fail to kill a minion with an auto attack, skillshot, etc. When I CS, I try to focus on who my minions are attacking (The ONLY minion you should be attacking). When I first started playing this game, I would just attack random creeps, but that didn't go so well. Anyways, hope this helps you.
