PoE Winter Orb, Melee builds without Occultist

Rough idea of the build, just the framework. I've had this idea for a couple leagues now, basically it's about how you can trigger Infusion for skills you are not actually channelling by triggering Infusion with for example Cyclone, while having a seperate Infusion setup with channelling skills of other damage tag types. The medium cluster notable "Rapid Infusion" gives 50% inc effect of Infusion, so for example from 10% more dmg of supported gems dmg type tag to 15%. With the 9 in the pob it becomes 55% more dmg for every damage
