Combo problems

So most of us use a combo to buff and increase zantei damage. But for me, this steals aggro from bosses, they walk toward me at something like 10m/s and then I usually either zantei too early or get interrupted. It's so annoying. I don't have impact, and I'm saving my book of oblivion for Tenryu. Is there anyway to counter this annoying problem?

Also, when I regularly Zantei, sometimes it doesn't crit. So I'd rather not use it alone.

 

-you need fix your playstyle
-note u need get hit or agro to get counter use zentai
-your crit rate not good put more crit from your gear
-for havey fast zentai combo
try meikyo - zentai smith - 1or 2 mp ender cons
-all about samurai use zentai is timing
- i m not useing impact to
- you not need obavilion book for tenryu cuz zentai build continue to tenryu

maybe u just worng chose job to play even with poor gear i you fix your playstyls and know how to get timing useing zentai. this what u get .
the biggest problem u need learn more. cuz out there all expert katana user not instan become pro. they trought lot trial and error. and time fix the combo. make good guide for us newbie to enjoy play katana build. so just dont complaints but learn it and fix it.
