The idea is to have a cyclone coc blade vortex character doing some 100% fire conversion with avatar of fire and gems/gear (brotherhood and phys to light is 100% i think, the math is confusing), 2h sword to get the most range out of cyclone, ele ascendancy to mitigate reflect, pathfinder to supplement damage, scion is right next to the extended duration modes which works out for blade vortex, aoe nodes in the witch and templar area, dual curse for maximum fire pen(or temp chains). My main concern is the build might be squishy, i dont really have a feel for what sort of overall percentages are needed but i was hoping with the right gear i could do pretty much anything with this build. Advice appreciated.

edit: this is also based around the assumption that %phys will apply before the damage is converted to fire and the %fire will convert after the damage is converted to fire. If thats not how it works then my damage is borked.
