Well, no reason a Sage couldn't also throw out a Miasma as well before wading in to lock everyone down with Visage. I guess my only gripe is that level 2 wizard spells are so competitive, between Miasma, Combusting Wounds, Infuse, Arcane Veil, Merciless Gaze, Blackened Sight...think it might be the spell level I value the most overall, personally.
Of course, I should add that I'm a relative pleb who sticks to Veteran because while I'm pretty sure I could handle POTD, I just don't want to expend the necessary attention and effort to play on that level, so my advice might not be the best available.
