The game's most limited character in duelling? Only two moves are used. And to top it off the Orochi's flicker abuse is chronic. Are Ubi aware of Orochi issues? I suggest it is broken and needs some serious re-working.
Its an issue on pc. In console, orochi has more viable moves. The general problem is, that spamming light attacks and in this case also zone attack, is too effective for the stamina consumption.
Not only that, the two moves are generally fast enough that blocking is extremely hard, so you get almost guaranteed damage. But the Warden is almost the same. Just throw the vortex in there and it could be the same guy.
