EZ crit baka

The concept with Baka and Qin's is that the build style goes hand in hand with his kit. Baka, like all hunters not named Heimdallr, doesn't have variable attack/damage progression in his basics, so the normal build style is to get very high base AS (approaching the cap of 2.5), to get the most out of both Qin's Sais and Butcher Blades. This makes him both a squishy and a tank killer.

Your build proposal mentions or approves of Ninja Tabi, Hastened Katana, Rage, Deathbringer, and Bloodforge, and replacing Ninja with what I assume you're referring to being Wind Demon. I'm assuming you're okay with the build creator's choice of Asi. While that can absolutely deal good damage, and when WD's passive is in effect you're getting pretty good attack speed, it's not quite approaching 2.5...it's 2.08 unless I've miscalculated.

The other major oversight here is that your build isn't incorporating The Executioner, which I feel is pretty core. Even though Butcher Blades does true damage, the rest of his damage output is subject to mitigation from protections, making The Executioner quite core.

When you build into a crit build, you're dedicating at least 2 items. If you want to deal significantly better damage against tanks as well, Exe needs to be there, which means something has to come out of your build. In this case, double-lifesteal (BF) would be the first to go for me. Otherwise, I'd settle for less crit chance and only get 2 crit items.

In any case, I still feel Qin's is a better conceptual direction for Baka. It allows more build flexibility and the high base AS target also allows Butcher Blades to be as effective as possible.
