I wouldn't like that many interrupts. I don't understand the purpose of the build? You have 3 spell interrupts and echo, you could replace them for arcane echo and powerblock for way more powerful shutdown and you free up 2 spells. Frustration fails expecially without enchant removal. The only form of shutdown are your interrupts but a veiled monk will laugh at this build and half cast their way through most of those interrupts
maybe fun with 4 interrupt 2 hexes, cop and echo for an hero to abuse AI.
for the rest, looks like you should try build before posting them, or think them over a sec longer.
