New KTN build, please critique

I'm not sure if it's just because I'm new or only at t3 but my DPS is low unless I get a parry with Zantei combo.

Pulse Blade>Pommel strike(save)>Meikyo(tough)

 

Looks about right for t3 only.
I want to recommend hasso to lv10 (as spam attack skill) but youre only 9 level away from t4 so just save the sp for now.

Since your combos contain meikyo ender I assume your crit is not 100, if you had spare spina you can buy "Seahorse Bangle" to change the "Beast Fang Talisman" 90k (1slot) as I write this.

nitpicking corner:
- Combo row 3 was not necessary, no need combo simply manual use them. Issen (consecutive) would not do lot damage.
- If youre okay with 0 defense, grab "Reflex" lv1 skill from Dual Sword, its decent opener skills can be used from long range.
