Nobody uses Arc. Prismatic has everything that’s good in Arc and more, AND it has survivability for all classes. Sure, Titans have knockout and Hunters have combination blow. Warlocks have nothing, and the other two have it tied to a melee or an aspect. Give Arc some good survivability, given how close you have to get to enemies for it to be effective. And don’t give us some awful damage res, like you did with frost armour. It’s so useless. Edit: Have the healing aspect of arc be tied to amplified, that makes it much simpler. Edit 2: While amplified, you constantly regenerate health proportional to your movement speed. At maximum, this should be roughly as strong as 2x restoration due to the penalty of having to be constantly moving. This idea plays fully into the aggressive playstyle of Arc.
