Brightshade armor piece sets should give it's set bonus when worn seperately.

[HeatAndRun]

Currently the brightshade armor piece provides you a 10% bonus damage against shadow-aligned monsters when you wear the armor and the helm at the same time. Otherwise there's no damage bonus you gain. Considering the dreadstone armor and helm's self-repairing mechanism works even when only one of the armor part is worn, this seems to be not fair since the brightshade armor sets are kinda an equal counterpart of the dreadstone armor sets. The 10% damage boost to nightmare monsters seems kinda interesting only when it's one of the unique character perk, but not so interesting when it's a set bonus of endgame armors. Why don't just give each armor piece 10% damage boost against shadow-aligned mobs? You can get a precious damage boost even when you're wearing only one armor piece, but at the same time you can get a quite meaningful 20% damage boost if you wears the armor and helm together when you really want to get more damage output.
