As i said in previous post that i will look into this...so i did!
~Updated ICE dps addon:
Fixed priority of divine strike(now it has higher priority then sonic strike so you will be able to cast second divine strike more easily and without worrying if you have moonspark stacks)
Thanks Yamini once again for pointing this out~!
Seems like the updated addon now prevents the casting of divine strike, cant cancel the cast even when i let go of rmb
