No, I was talking specifically about the ones that drop from Primordius, or Lei Shen. They both have 2 sockets, instead of the 1 socket on any tier glove. One drop has +mastery and one has +crit, versus the +haste on tier gloves, and the socket bonuses for both are good.
Sure, it's a wash in *total* stats, but if you gem pure INT, I believe you wind up with more from the offset gloves (from memory). If you don't gem pure INT, it still leaves with you a little bit more customization room with your gems. That and I don't gear for haste.
I do suppose, however, the Shadow gloves would be quite nice (mastery and crit), and would help more towards building an offset...but (and I haven't researched), wouldn't the healing gloves actually be better for Shadow because of the haste? /shrug
