Attack move and why its useful

how to bind attack move to left click: http://www.reddit.com/r/leagueoflegends/comments/1bo2nk/guide_to_easy_kiting_left_click_attack/

Attack move really helps in the laning phase when you're a ranged champion because it allows you to hit creeps and champions at maximum range while respecting your opponents pressure and is really good for chasing bringing out the full potential out of your abilities which means no more facechecking bushes . It really improves your poking (teemo).

Reason 1: If you can attack at maximum range then there is good space between you and the enemy champion so that means more health which mean more gold and sustain in lane(my favorite). Reason 2: You can kill champs easier when youre chasing them. Go to this video to see what i mean: http://www.youtube.com/watch?v=dgMMxTofZ5A Reason 3: as previously stated you don't need to facecheck bushes anymore because you will deal damage to that enemy at max range instead of having to keep tapping that right click and you can chase better in the jungle.
