Backstabber is a great item, but it falls of late because of its nature as a t2 item and non-scaling.
An interesting idea would be to make it even more backstabby, as in an upgrade that gives your melee in the enemy back a better effect. Melee already triggers Backstabber so it makes sense to me as a concept.
Critical Backstab, t3 Gun item, upgrades from Backstabber.
Same stats as Backstabber, but with a small added Spirit scaling of 0.05 on the DPS.
Melee attacks in the back triggers a critical Backstab, dealing 25%+ melee damage and further reducing Bullet resist by an additional 12%. Applies the basic Backstabber effect as well but with 8 second duration instead of 5 seconds.
The fact that the item would have 2 cooldowns is a problem, but I feel that it would provide a dynamic and fun incentive to truly hit people (with your melee) in the back. Melee items are also currently a little underexplored, there is room for at least 1 more.
