Well, i havent pvped much so my advice might not be that valid, but ill tell you what i think.
I have a sadhu2 and unless they buffed it recently i dont think this will be good for pvp. Any hit takes you out of oob and if you are considering using safety zone to counter this, there is too many ways for them to counter safety zone especially when lancer is released.
Maybe with the mackangdal it could help, but i dont think it would work out well.
I had a cleric pvp build in mind. It was Cleric2>bokor3>oracle>kabbalist. This was before i heard of the rank 8 classes though so maybe id change it a little or add kabbalist 2
EDIT i just realized you are already at sadhu. If you dont want to reroll then i guess my advice doesnt help lol. You could always do the same build i mentioned except put sadhu in insead of the last rank of bokor.
