Honestly many classes have too few good attacks avaliable in 1vs1.

Orochi (my main) for example has only top light and and zone attack, evrything alse is just a free parry for his opponent.
Suggestion: move hurrican blast (the charged unblockable) from deflect followup to C, this will allow orochi to pressure defensive players forcing a parry or a dodge
and overall improve the variety of attack which is always good for making combat fun and not boring.

Other classes with few attacks variety in 1vs1: kensei,shugoki,raider,berserk.

Also moving warden shoulder bash to an input similar to nobushi (C+ guard break) with a small backward momentum will balance it since this way it becomes more difficult to spam and a bit more easy to react.
