After been studying all characters i found Orochi has no unique skills like other chars.
Key features of Orochi are:
-Deflect: It's common to every assassin
-Unblockable counter: Again, common to every assasin, but zerker who has his own counter style.
-storm rush: Not unique since valk, who has a, in my opinion, a better version of storm rush.
These left us with Riptide strike, with very limited use, and storm gust, completely useless in pvp...
Then... which is the key move of orochi?
Every move that you listed is a signature move... it doesn't need to be one and only in the whole game to be a signature. You've got your understanding completely wrong.
Storm rush is not the same as the valk's move, they just have something in common.
What is more interesting here, is what is the purpose of the whole thread? What will you get out of it, because I find it completely useless?
Well what unique move does PK have, since if you go that path, you can safely say that it is the most stupid class in the whole game. They have absolutely nothing except the bleed effect which is not even a move.
Orochi is classified as an assassin so it is safe to assume that the way you play him is similar to the other assassin's. Except that he has amazing moves such as the storm rush and the riptide strike which are much better than anything PK or Zerg can offer.
PK have stabbing grab, she can cancel any heavy with a light attack and grab while running, for example. And for my like, chains with heavy finish, she has her "semi-storm rush" with its own utility (please PKs... stop stealing my executions) and is faster than Orochi. In fact, there is nothing a Orochi can do better than a PK. Maybe storm rush... i don't try to emulate storm rush with a PK, only with valk (with better results, in fact)
With enemies with a minimun of skill, Orochi is almost useless, have no tools.. For been an aggresive hero, have no skills to be that.
A pair a weeks ago i found i could play other heros just like a Orochi with better results (PK, Wardn, Valk...) I'm trying to prove myself wrong
Well, I guess that you are not an orochi person after all. I tried PK couple of times and found out that it is the most boring class possible. The only thing you can do with her is spam light attacks... that is just about that, end of story. The heavy cancel into light is again a light spam. Stabbing grab is just a GB like every class has... nothing so special about it except the bleed.
I think that you are mistaken about that semi-rush - there is no such thing. I guess you are talking about the forward dash with top hit which you can parry 90% of the time but every class has that.
The bottom line is, that if you really need convincing that you should play orochi - then it is quite obvious that you shouldn't.
Cheers!
