I'm reading your opener and want to understand the difference between your choices and mine.

So what I'll do prepull is pop acceleration and diversion, then hard cast verthunder > dualcast veraero > flèche > verfire > verthunder > contre-sixte > then the rest is based on procs verstone if I got it in my first casts, verfire if I have that, rinse repeat until I can manifaction and to the melee combo and embolden during that combo to try and get it off with trick attack and finish it off with my appropriate verflare/verholy and usually acceleration the opposite mana.

I notice you do hard cast verthunder/veraero then dualcast the next level spell of the same mana color. Is there something I've missed here that's losing me damage in my opener compared to what you're doing?
