Rebalance Vibro-blades Please

No matter what I hear it always seems to be that vibro-blades are meh. Now I’m -not- here to suggest how to fix them because I haven’t the experiencr to do so. I can’t suggest any feats or any thing that works with rebalancing vibro-blades. I do know blaster pistols and dual blaster pistols + duelist + flurry are maybe too good. And I feel that maybe vibro-blades could use a feat like Duelist. But since I’m not the man with all the data behind it I suppose its up to people who know the mechanics and math by heart.

Case in point I still wish Poisoned Weapon didn’t destroy a blade after being used as that would have applied some sort of DoT which would have increased the damage output but meh. Whatever.

Only thing I can think off is:
Raise the avdam of vibro-blades to be stronger.

Allow the use of Cortosis Weave(?) Not sure about this one.

Not sure how much avdam vibro-blades need to be just -there- not underpowered or overpowered but just there.
