How to effectively run it down mid.
As soon as you join the game use your teleport on your middle tier 2 tower. Right click the enemy fountain. When you respawn use your ghost and right click on the enemy fountain. Repeat these steps, if done so correctly your team should be flamming you and afk in fountain waiting to ff, do not DO NOT stop doing just because of someone else's opinion. By the end of your 20minute and 1second game, you should have 69 deaths if don correctly.
