On the Nathan problem, yes he does have the potential to become extremely powerful. However that power is tempered with drugs and the notion that his powers are highly destructive, unlike Nathans "nemesis" that will hopefully appear later in the rp. His powers are unfocused, like rage itself there isn't a sole thing that he can focus it on which makes most of his more powerful abilities more AoE than single target battles. 

Plus the expenditure of said power causes massive bodily harm and will eventually kill him if he doesn't control it.
