L's Minor Drain and Vamp' Touch are being over nerfed?

"Larloch's Minor Drain and Vampiric Touch now only heal if the target is damaged, neither can be self-cast, VT can't be cast twice on the same target, and the Bhaalspawn LMD does the right dam."

I can only see this as an unreasonable nerf, compared to other classes who has Mirror Image and can withstand huge punishment.
