After you pick up your Rageblade from that warped little goblin bastard in the shop you are going to need attack speed to help get stacks on the blade. Since your W gives you additional movement speed and Kayle is not reliant of landing crits in order to do massive damage, zeal is fairly useless. People that I see go Trinity Force Kayle really rustle my jimmies. if you notice the other team is giving you funny looks you should get Wits End because it reduces magic resist and is plain freakin awesome, but if you see that the other team isn't really applying that much pressure on you and focusing other members, then Ionic Spark will really help your damage input in team fights. HOWEVER, since Kayle's passive already reduces magic resist you should only get Wits End if you notice the other team picking up MR (magic resist).

E and then you marine stutter step micro in lane and watch as everyone ragequits and then QQs. If the lane opponents are being super mean then you get more power on your Q so you can poke them if the get too friendly and then back off, also use your W for speed and not healing, because of its massive mana usage you can only really span W mid to late game.

Avoid mid if Ahri is there, or any other far ranged ADCs like Sivir or Nidalee because Kayle is fairly Squishy and doesn't have the range to compete for a competitive mid. Oh and don't be a douche. Your Ult is to save teammates not to justify you turret diving into everything and having a teammate die to help bail you out. If you don't conserve and be pro with your R, expect a lot of this...
