Okay, Kayle was the first ever champ I bought and I still don't know how to use her, what is she good for? Are there any good builds for her? Did she get nerffed ?(that would suck) is there anyone that can help me? Okay, I like to use her but her moves don't seem to help in team fights, and I can't carry a lane or even sup well with someone in my lane is there anyway she can?
Her main skill is obviously her E which makes her a hybrid type of champions and I usually build a Zephyr on her for the multiple bonuses and depending on who you first Wit's End for more Atk spd and resistance Her kit consists of AP/AS types but its really up to the player and how the game is progressing.
What Rhyto said is completely true. I would like to add something to it though... Best item on Kayle, ever, is Nashor's tooth. I like taking her top, so I max her Q first generally for the free harass on most champs. Because of the amount of slow it does, most champs will just take the (massive if you have any AP) damage, a little AA harass with the E proc, and run away, or they may try to close in on you. In which case, you have your heal/speed boost to get out of that.
Thats all I have to say. GLHF
Kayle is a very good champion that can burst priorty champions easily. She can be kind of tanky has well. She is an hybrid and can do any role with ease. each role will have a different build and play style.
I would try her in the mid lane.

I would take Righteous Fury at level one and max that first, then reckoning at level two (max this second), then Divine blessing at level three (ultimate whenever).
You Can use your E (Righteous Fury) to help last hit and harass enemies from a distance. The Q (Reckoning) Can be used has effective poke and a very bursty spell which can do a lot of damage, you can also use it to slow enemies to catch up to them. Your W (Divine Blessing) can be used to heal, and speed up you or your allies, it is a good support spell. The ultimate (Intervention) should be used to prevent you or your allies from being killed. (the most annoying spell).

Hope this could be useful.
kayle can play as either a top laner, mid laner, or support role. although it is possible to build ad with Kayle your primary items (top and mid) should be focus around ap and attack speed (guinsoo's, wit's end, and hextech gunblade). building durability with kayle is also a good idea; health, armor, and magic resist when necessary. when playing Kayle as a top or mid laner level your E ablity first then Q; as a support level W first then Q. although Kayle's ultimate can be used to save an ally from near death it is best used on your ally that is taking the most damage.
