I was mostly referring to generating White/Black Mana over time being the main reason to have a DoT. I figured it would be a single target oGCD or an alternative weaponskill finisher regardless though. I'd much rather see a straight Osmose oGCD that grants RDM more mana based on their missing MP to solve their mana issues. Not that they couldn't be combined, but I figure the DoT would see more use.
