AP Xin Zhao still viable?

Not full ap but 1 or 2 items work.

I've seen it work in a normal game.

Most xin players I see take Guinsoo's regardless, but I've seen a few just go straight AP and it worked.

Not since patch 6.4 when they nerfed his AP healing ratio by a whopping 43% [(70% AP - 40% AP)/70% AP] and his attack-speed bonus by 25% [(80% AS - 60% AS)/80% AS].

The hybrid build is still sorta okay, but Xin just no question works better now with the + tank and + tank builds compared to the hybrid build.
