User blog comment:Unevent/Hybrid items!/@comment-3974211-20130520081648

Xyph is saying he wants hybrid items that promote hybrid gameplay, which is what items like Rageblade and Nashor's Tooth do. Gunblade does not promote hybrid gameplay, it merely supports mixed scalings.

His problem with hybrids is that they typically have less than favorable scalings to compensate the fact their items are twice as efficient. This has the knock-on effect of the items being half as effective on people who don't have both the scalings.
