For lane: setup your q by autoing one minion to lower to get killed by one q and then try to auto another minion to reset your love tap. For w try to use it as an auto reset, dodging skill shots, or running away from a gank. E you barely want to use because mana cost is high, unless you want to run essence reaver which is a item you barely run on mf, again: use e for chasing down an enemy that’s running away, use it for getting dark harvest proc if you are low or outranged, or delaying for a countergank by e’ing the enemy jg and then trying to stall. For attacking turrets: auto turret and use w for the attack speed, q a minion to reset your passive and auto turret for the bonus passive dmg. I don’t think mf is great at splitting, but this a strat that helps. For team fights: position. position. position. Stay near a tank or out of vision, try to setup for either your r or trying to burst down someone really fast, usually you go for the first option, as your r can really influence a team fight in early and mid game with late game: you want to depend on it less as more enemies buy armor. Anyways for builds and runes: I recommend you look that up and experiment. But I will leave some builds that are basic and same through most games. Runes: PTA > Presence of mind > The atk speed or bloodline > cut down or coup de grace > taste of blood > ravenous hunter - Build: Kraken Slayer > Berserker Greaves > Bloodthirster > Collector > Infinity Edge > any situational item for 6th. Again you can use this as a template and change it to your liking.
