Suggestion: Blasphemy Improvements (ED, Contagion)

Even after the buffs to Essence Drain and Contagion, its really not worth manually casting them compared to most builds outside of boss encounters. I think it would be a good idea to allow Essence Drain and Contagion to be linked to Blasphemy instead of just curses. This would allow you to opt into a pseudo damage aura that is currently missing from the game. It would also be nice if the radius of Blasphemy was increased a bit since its barely larger than melee range without support.
