Only noobs like to wear level 50 armor at level 1. If you add a level requirement before you can wear the gear it not only shows you at what level the person is at a glance but also gives players a goal to shoot toward. For example: "OMG it's such-and-so armor, I really wish I could wear that. You know what, I'll get to 'X' level on such-and-so job so I can wear that bad ass armor."
