"Blood Pact" Potency?

SMN have had "Blood Pact" Damage items for quite a while now, but I feel like there's something missing for BP Wards. It'd be nice to have new items added which would enhance the effect Blood Pact Wards (which would clutter even more inventory space), or change the existing Blood Pact Damage items to affect enhancing and curing wards as well. This would be geared more toward existing lower level Blood Pacts which never really improved or aged well as the levels increased.

Some prime examples would be:

Current +1 to AGI, INT, MND, CHR

And so forth. What do you all think?
