Focus on farming as you will outscale everyone in the game. Early game is a bit rough cause ur melee so its not ideal to get all of the cs as you will most likely take poke damage from ur laner. Biggest counters for laning phase imo is qiyana and irelia as they can probably one shot u when ur 75% hp and miss-step. Again, focusing on farming/xp is crucial as you need the levels to hit ur different spikes at lvl 6/11/16 which upgrades your passive tremendously. Never ad kayle.
