Why do people advocate that radiation weapons are best in slot for drone Zane mobbing?
For general usage, you want the drone bonus (cryo) damage to be on a weapon whose element covers the weaknesses of cryo. This minimizes elemental penalties between the 3 health types. Since shields are the only health type to resist cryo, that leaves two options: shock and radiation (kinetic as a neutral element is third). Looking at the multipliers (assuming cryo damage ratio of the anointment is 1 as it is today), radiation seems to be more level:
… but remember that non-maliwan weapons have a smaller damage multiplier for rad damage (.75) than shock (.8). Incorporate that and we get:
Ignoring the DOT, radiation doesn’t even out damage a comparable kinetic weapon. On multi-bar enemies, assuming equal hit-points per bar, a shock weapon has better average raw DPS than a rad one in all scenarios except multiple health bars.
Obviously for Maliwan weapons, without differing gun damage multipliers, rad is a more attractive element. With either shock/corrosive to handle immunities or fire to really maximize health damage.
TLDR: why is radiation the prefered element for drone bonus damage? Only outperforms shock/kinetic in niche cases on paper.
