I have been pondering over Shinobi and Goon a lot and it struck me when looking at the synergy of my build out side of a DPS context.
Shinobi is a Tank.
Bunshin alone allows for a high Con build that lends itself to burst damage of a considerable amount.
Edit: That is to say with bunshin OFF you can tank and while using Bunshin you can burst.
Shinobi benefits greatly from Con and Dex, which Tanking does also. Mijin is really a viable option for High Con builds. Kunai is ranged coupled with Provoke attribute that is very good taunt. from what I seen mokton is multiple targets of various distance and you avoid an attack, thus another hate generating method. Katon is another source of good hate. Shinobi seems like a very viable AOE tank.
Edit: As for stealth, this is good especially with mijin in the event that you need to shed hate
I am going Sword> Pelt >Hop2> Cor1 (Going2) > Shinobi
I will have to test a High Con/Dex build when it is possible for me, damn flower since lvl 110 I have been camping it on and off when able.
