As the level of gear gets higher, the stats increase, or change, variably, with something else taking its place.
With the Jade boots, what happened to the incoming healing stat? Not that it really bothers me to any major degree, but I do feel a little put out that it was just taken, and not replaced with anything. As it stands the incoming heal stat, although not significantly, makes the lower level boots better.
I see what you're saying about the boots, but I don't think it was an oversight. I interpret it as the developers' way of saying "OK I get it, you want to turtle tank with exalted level gear. Well, the cost for doing that is you can't heal others or yourself as well. Don't like it? Then you have to have lower health and resist."
