Damn near every good rare armor or shield has a level requirement of level 101 to 140-ish. Gawd. Some of the really good armors/shields should have level requirements of 170+, more motivation for people to level up...and there would be less noobs running around with duped red rings, SS shields, etc...

Some weapons should have level requirements too. :/
