Salvaging/recycle Ancestral weapons (shatered) should give stygians shards !

Currently the shatered ancestral weapons you get from bosses and from summoning souls of bosses, AND from sellers (against stygians shards) give only iron and scourgestone.
But those weapons stats are random and it's really rare to get the max of one of the stats.
This means if you want to have a maxed out weapon for your playstyle, you have to farm the resources to summon 50-60 boss souls to get the chance of finding the weapon that correspond to what you want and the chance of having the stat you desire, and the chance to get this stat maxed.

After killing every boss and farming 100+ lesser souls and 20 higher souls i never dropped any legendary ancestral weapons! This should be bumped a few percents along with the chance of getting the epic ones (only got 2).

So making the classic shatered ancestral weapons recycle into some stygians shards would make this whole process less painful because all the useless ones would help buy another one from the weapon class you desire !
