WAIT - maybe I'm thinking of something else. Is it possible that they disallowed the ability for, say, +3 to Fury (Barbarian) and +5 to Arcane Power (Wizard) on the same item? That must be it, because you get zero benefit from those, at least the primary stats are doing something.
I know that you still get SOME benefit from them. I also do not expect all items to be perfectly itemized. The question was, didn't they make a change so that you did not get two conflicting primary stats on the same piece of loot?
I could have sworn I'd read a patch note, a blue post, SOMETHING recently that discussed fixing gear items like these:
In both cases, one of the affixes is wasted because only certain classes properly benefit from certain stats. An item shouldn't have strength AND dexterity on it, that's just silly. I thought that this was addressed... but I keep seeing it happen. I'm I making it up? Maybe it was an internal build fix that never made it into a beta patch?
