Damage differences aside, the reason why I wouldn't use lightning is because of it's aoe damage. The last thing I need is to have 5 more monsters on me while I'm lagging.
I agree. What most people don't realize is that when you cast a fire nuke with the lightning imbue, you still get AoE damage from the imbue. That doesn't really fit with the point of the fire nuke as your first strike at range; you don't want to start pulling mobs toward you before you even have a chance to set off your second nuke.
I also have the lightning imbue, book three, on my level 34 nuker. I'm using it for now because I don't have the SP for the fire imbue, but I don't plan to delevel it because it's still useful for killing lower-level mobs when a nuke would just be a waste of mana. If I ever get near the level cap I'll farm up the SP to max both imbues; I have the mastery anyway for the nukes.
