New Kayle build discussion

Just a theoretical build I want to share with you guys while I'm in China （so I'm unable to test this build out, I just want to see what people think about this).

Kayle's passive already demolishes tanks' resistances, but combine that with Black Cleaver and Wits End and a hybrid build focused on attack speed and she becomes a real beast, outputting tons of damage while peeling and killing tanks like no other.

I'm thinking about building her like this: -Nashor's tooth (or Zephyr) -Guinsoo's rageblade -Wit's end -Black Cleaver -Trinity Force （gotta have the tons of damage) -Boots of some sort, probably Ninja Tabi to make up for the lack of armor in this build -Probably no defensive items as her ult and heal can keep her alive even while building full glass

For rune I'm thinking: -AD quints -Magic penetration marks -Armor (per level) seals or scaling health seals -AD (or AP per level) glyphs

For Masteries I'm thinking 21/9/0 putting points into both the AD path and the AP path, getting 4 points in attack speed over CDR

If some of you could test this or better optimize this build, I'd greatly appreciate that. Otherwise, I'll be returning in August and I'll post my test results.
