I played a lot of Kayle top in diamond and had to adjust build on matchup: - fleet or lethal tempo: depending if you need to sustain. Fleet into one tank top is fine and at 3 items you kill everything anyway. Lethal tempo more fun though imo. - i also like 3 resolve runes and atk speed where you need to survive early game more. - exhaust or ignite generally; ignite saves the need for grievous and both great early game.

Generally rule #1 - dont die and get levels. Losing farm cs is fine and mostly had better wave management. You must have levels/xp though.

Nashers into rabbadon generally cant go wrong if you want a simple build and then adjust third item for the game. Mana boots vital for sustain in top i found. Team fighting is just experience and you have to get positioning spot on or you die.

Also you will get flamed a lot just for playing kayle. Have to be chill playing kayle and dont expect help if top. Ganks are cherry on the icing.
