yeah, stacking different forms of reduction/penetration reduces their effectiveness because of the order they're applied in. If your reduction gets them to 0, your penetration does nothing, and if your flat penetration lowers them too much, your % penetration does less. It's a rare boon for tanks who get owned by LW and void staff imo, but it can be a pain for dps to determine which to build in which situation.
