For the purpose of making some of the new 119 abjuration armor certain armors are hard to come by for crafters. For example Cursed Cuirass is a gold smithing recipe but requires a Darksteel Cuirass which is a black smithing recipe more than 10 levels over the soft cap of 70. It wasn't as much an issue when you only needed to get a high quality on the original synth, but now you also need to high quality a second time in order to get the Voodoo Cuirass. With the need of so many Darksteel Cuirasses it would be very helpful if they could just be purchased with sparks.
That being said if the Darksteel Cuirasses set, Dragon Mail set, and Plastron set were added to the sparks of eminence rewards I would really appreciated it.
