Yeah. I'm seeing the flaws in my logic. I'm working on how to balance it out. I'm thinking along the lines of Karthus Requiem in damage and scaling for ult, with the cost being a large sum of health, and the healing from the marks being lower(the current plan has it as being able to go from 0 to full potentially) I may even rework it to a global skillshot, ala lux, although that would make him more of a potential carry than a tank i'd think. As for the W skill, may rework it, may just increase the scaling a bit. I don't want it too strong, but don't want it useless either. I have it slightly lower than Karthus's DOT Field, maybe i should just have it equal to karthus's field, although the slow seems to make it too strong if id do that.
