Just to clarify, you're saying that under your concept of Horizontal Progression, every alternative is completely viable in all situations, but any particular item may have a slight advantage in certain situations. Is that correct?

Would you be able to quantify at what point that slight advantage becomes too much and now that piece of gear is necessary for that certain scenario? Is that a 1% advantage? 5%? 10%? Once an item goes beyond that margin, is it now vertical progression? And is it vertical progression just for that particular slot, and horizontal progression in other slots if they're still below that margin?
