At the begun dont be so agressive. Look to farm most you could till you jungler dont gank your lane. If gank pass correct then you should B and buy. When you come back then you can be agressive player with buyed and placed ward. In them battle 1st kill carry or AP carry. Then you should get jungler after him strike on the tank cause u will be available to kill him instant.

Farming should be done with 1st power. U need to be very carefull if u dont kll minion or something else then will be very big cooldown. If u had problem with cooldown buy boots for cd.

Summoner spells are best with tele. and exhaust but if u go top agians voli or mundo then is better ignite than exhaust.
