Void Ark... Players are getting sick of Palette Swap Gear.

[BreathlessTao]

Got tired of palette swaps ... oooooooh I don't even remember anymore. Several patches before 2.x even concluded. So yeah, too long ago. -_-
And

The Question to the Item Team Lead thread is still taking questions; feel free to ask them why they keep making healers and casters just a lazy palette swap for gear.

...it's not like we have to ask them why. I think everyone understands why it's good from a dev/design point of view, that's not the point here. The point is that it should stop (or at the very least, decrease), but it likely won't exactly because it's easy to do, takes less time, eases the workload on the small dev team, etc - those old chestnuts, y'know.
