Maybe in a general sense, but I think that people fight a much less variety of opponents then they might think.
For example, if you are a playing a WM warrior, you might spend most of your time fighting necros and invokers. In that case, the eq slots used to boost HIT are mostly wasted. HIT should be sacrificed for mental and some afflicitive saves in this case.
Likewise, HP gear on a caster is wasted against a shaman.
