Shirk is not -always- the answer. It -helps- but there's going to be points where the Samurai is still nipping at heels. I've done this numerous times with my static to the point that my Dragoon sometimes pulls away from giving me Eye due to potentially ripping hate. Diversion does nothing because a good Samurai practically out DPS's its effectiveness.

I wouldn't say put Enmity Dump on Seigan because we spam that move on unavoidable damage(or good Samurai should be). Rather, it should be attached to something like Yaten(somewhat similar to Elusive Jump). The only time you use Yaten in any fight is literally if you cannot run away quick enough or the break between that GCD and the next is long enough for you to run back and start up again. As such, putting it on Yaten would make us use Yaten/Gyoten a lot more.
