I'm sure players would have appreciated being able to buy cool-but-inefficient items, if only the system made that not a losing proposition. By the same token, players never seemed to want to spend money on mounts or other cool-but-inefficient stuff. (I could say the same thing about castles, etc, but that latter bit was more my running style than rules issues.)
MIC resolved that issue to some extent. They realized that players are always going to opt for belt of strength over any other belt, so they gave us the best of both worlds - being able to (effectively) combine your belt of strength and belt of battle together at no extra cost. Same for the other stat boosters.

Probably a little sloppy, but that is perhaps the most efficient fix in a setting where the importance of the big six was already deeply ingrained, and it was not possible to wean players off them without giving the rules a complete overhaul.
