Do you understand the other two grimoire options are the PVP talents atm? (i.e. not supremacy)
Some constructive info for you.
Get rid of Howl talent; its on the same DR as fear. Coil is superior for PVP atm.
Get rid of Blood Fear, having fear on CD is not a good thing and the free dispell/trink talent whips its ar$e.
Get rid of supremacy - for obvious reasons.
Glyph the HS and not an extra shard, which is of no use.
This might help you to start with.
