Just thinking of a new build for Kayle as of patch 5.22, and looking for some general feedback.
Core: 
+
(two really strong AS+on-hit items that synergize well)
Defensive: 
(Zeke's is great if looking for a team oriented defensive item)
Offensive: 
Situational: 
Example build:
So, thoughts? opinions? Anything I'm forgetting, any items i should skip?
Blue Kaozi3 votesI think gunblade will be extremely strong on her now that she can heal off of her e. Get her low? She ults and heal to full before it ends

, good for taking down squishies fast and good AoE Damage overall
junglerboy161 votesHuh, so that's a more hybrid build then? Personally, I think the new rageblade is too strong to pass up (it's basically half the damage of your E on top of a ton of awesome stats), but I haven't seen anyone suggest Runaan's or IE. Having a lot of crit and mixed damage could be good, but the amount of AS Runaan's lost makes me not favor it that much, especially since Guinsoo's gives wave clear/AoE now in its place. I'll still try it out though, thanks!
ltmetal1 votesThe Lich Bane update benefited Kayle bigtime. You can easily replace Gunblade for it in any build, since the CDR and Mana allows you to spam your heal anyway. I definitely think Rageblade and Nashor's are core on her though. Here's my recommended build:
6th item is flex, but you can also swap out the Deathcap for one of the items below as well.
Never tried building before, I hadn't considered that it could work. I would even expect that after the Zhonya's nerfs, Harbinger might be a better option.
junglerboy161 votesYeah, I play Kayle as an aggro support sometimes, so that's when I usually get it. If you are the jungler or mid you can still get it though because the passive is so strong on an AP carry.
The main reason I consider gun blade a good pick on her is that it allows her to heal off of her E AoE and Guinsoo's AoE (as well as all of her on-hit effects). With gun blade, your heal serves as a speed boost more than anything.
PapaGreg211 votesConsider getting Rylai's for your third item. The slow is great for keeping enemies in place and you can always use the health and AP
junglerboy161 votesDoes it apply to her E's on-hit?
If it doesn't then it's completely redundant with her Q (which already has a slow on it).

If you use your slow (q) on a target the rylais passive will have no effect as the more dominant slow is always applied. However the passive does apply to her e on hit so you are applying an aoe slow consistently to the enemy during team fights. It is pretty dominant
