Is this set worth it for a Spellsinger?

I have to give up my Thunderforged Armor which is +1 Profane to DC (and I'm now forced to wear Robes, instead of Medium, so my MRR cap drops from infinity to 70?)
I do (sorta) upgrade my Many-Pouched Healer belt to the Silverthread Belt
I lose my Efficient Embolden -2 from Bluescale Gloves (as well as the -10% but that's easier to replace)

All that to gain +1 to DC and 50% spellpower?


Hmm, nevermind, answered my own question, this set is useless to me.
