Is it worth it to break up the spellfire set to get the belt of blasting? I see it on our ah for 1700g. At first glance it seems to be worth it. 23 Spell Hit and more spell crit. With the +spell hit I could replace the spell hit gem i have on the spellfire belt with a +spelldmg/+spellhaste gem from the new sets at Shattered Offensive. What do you guys think?
