Remove the healing debuff that viod has and make it life magic. Make the duration of the spell last only for 1-2 min max so that is 1v1 duels is something that must be reapplied to keep the fight balanced and in pvp it becomes a tactic that will be necessary but not over balancing. If it only lasts for a min a group may get the edge starting out but if they don't use strategy correctly and forget to redo it that person gets the slight edge from extra health from chugs.
That right there would help even out a lot of the balance issues.
