I play a very similar build like yours and its pretty fun if your used to go in melee range with your ranger.
I go a bit more in defense like this

RaO suits the build pretty well and with the lower cd you got a lot of movement.
But i think the main problem is that you can avoid the burst pretty easily cause the enemy will see if you cast your signets.
And if you try to stun the enemy with hilt bash the critt is gone.
Without the signets your dmg is just decent but not as good as other melee fighter atm.
Not sure if this build can be played in a higher pvp matchup but sure its fun in hotjoin
or solo wvw
