I think that's on account of Redgull criticals being OP in general, Overload's damage formula probably doesn't help this at all.

There's two ways you can go about this, Nerf Overload's damage per stat ratio and hit just the one skill, or address a problem that a few people in the community have with lightning criticals, in that they do a hell of a lot of damage, and nerf that instead.
