roger that.
I wouldn't be quite that quick to write it off. There's, somewhat unfortunately, one precise difference which made me go for the Digital Deluxe - you gain another 3 character slots. With the normal edition of RoS, you get two more, up to 12 slots total from vanilla D3. With the CE / Deluxe, you'd end up with 15.
May not be of value to some, but to me, that shit's important. Means I can have all my softcore and a better selection of HC chars on top. Might even have space for a mule or two.
It's up to you. The transmogrification plans, spectral hound pet and the other stuff for Blizzard franchises, well... most of that is just cosmetics. Up to you. But 3 more char slots is tangible.
