There are few mages who seriously want Mana or MR on their jewels instead of other priority mods like FCR, DCI, EP, LRC, Magery, etc. It has no FCR, which means you have fewer options for choosing other parts of your suit to make 2/6 mage suit.
Still, it's got 3 mods with over-capped intensity, some people might find MR 3 and LMC 10 useful for their cheap mage suits.
