I like the idea of changing Dualcast into 'reduces cast times by 5s'.
This will have no marked effect on its core rotation, but will nerf Verraise into giving it a 5s cast time minimum, and forcing its use with Swiftcast.
This'll help it's 'raise tax' situation, and allow them to increase dps a little or make Embolden affect all damage.

I don't agree raises should be a role skill or given to BLM. It's useless without Swiftcast and Swiftcast is too important to BLM rotation already.
