Pally: Blast vs Divine charge?

I think Divine Charge is nearly useless. Its only use is doing a bit more damage on neutral monsters. Every damn monster lv150+ isn't even weak to it except for Skelegons, and their HP:EXP ratio is worse than the stuff in Time Temple. I regret adding so many points into it when my SP reset from BB, and I might reset it once more SP resets come out.
