Currently I play a necro in draconic with 56 DC's. I have never tried shiradi and on live I don't care to. With the new enhancements I think one could potentially get great DC's and get the archmage MM. So, my questions are:
What is the main stuff out of shiradi that make it worthwhile? Could you twist in rainbow and double rainbow for the MM SLA's and it be worthwhile to be in magister as opposed to draconic? Are those two twists where it really shines?
