So here's the deal, my character is as follows.
Server: Argent Dawn
Class: Death Knight
My Death Knight is an Unholy Tank, but WoW-Heroes recommends DPS upgrades/enchants instead of tanking enchants, thus lowering the score of the enchants I currently have on my character, and lowering my gear score as a result.
I'm not sure if this is a bug or if it is working as intended, but I hope it gets looked at
