The regulars seem to have the argument that optimization would currently force two sets for healers and dps. I concede this point, it is true but it is an extreme. Can a healer in say max power switching over to dps be as effective as a dps dedicated to it, no, but what is the difference, probably generously 5%? Easily enough to want groups to look for specialization for hard operations but easily enough to get the job done in all other circumstances. Reversing the idea, can a full dps switch over to tank tree and be around 5% off a full tank? Can a tank in full tank gear switch to a dps tree and deal even close to 5% less damage from a pure speced? The discrepancy should be obvious.
To address the single armor idea, it would not be the solution I would have as while it would make certain points of life easy certainly I would think it would lead to a more boring game in the long run. If everyone had a single set of equipment to go for it would make equipment hunting seemingly a lot easy and sharing a lot easier and suddenly 95% of the time sink on the mmo. But that is just my opinion, and could probably be worked around. Heck might be just the innovative thing.
