I think this was a really good guide. I've enjoyed it a lot, and now I'm very hard to take down.

One thing that you can put in your guide is a champ match up is against Ori. She is able to harass you if you dont have your e to harass back. A tip is to try to anticipate where Oriana will throw her q because if you can you can poke her back with q. She will poke you with q -> w combo. What i suggest is that you play safe untill she is out of mana or if you can get your jungler to help you out by forcing her to go back.

Hey, what do you recommend as the enchantment for the boots?
And if i'm building Zhonya's for the 6th item, should i take sorc boots?

I think she works really well with an aggressive runepage - Hybrid pen marks, AP quints, MR or AP glyphs and armor or HP yellows - but Kayle can be built in just about any way and still be effective

This comment made my day.

I really want to start testing Kayle support once more! But I am not sure what to opt for runes.

Fair enough, maxing either first is fine, I think maxing Q is better if you want to harass more because the Q scales better with levels, and you'll still have maxed E by the time you've got runaan's anyway.
EDIT: and I think maxing e first is better for when you just want to farm haha

Oh by the way I just realized most koreans actually max E with this build. But yes, you're right: attack speed is the most standard pick.

Thanks buddy :) Will ammend it now

Yup, 9 is the earliest! ^_^

@Maintained, I pointed out I forgot what levels stuff got maxed :P Is it level 9 at the earliest?

@Vynertje, you could go hybrid pen, and I'll put them in as an alternate, its just that whole build works more if you have more Attack Speed - its the same reason why zerkers are prioritized above sorc shoes. The faster you attack, the more stacks of Holy Fervor you can put onto targets etc etc.
But I will put it into the guide, and I'll credit you :)

Any reason why AS marks > hybrid pen? Since you're building AA-heavy getting some armor pen would be great in the early game.

Damn Koreans.. they have so much skill they max an ability by level 8. :(
