Just given the potency at which Isenshi, Overload, and Exgalfa come out, I'm inclined to agree with the damage debuff. In theory there's plenty of options to space an Evoker who's advancing with CM/HSDW -- usually with Geist, high movement, or knockdowns -- but the people who can't will most likely die in one hit if they can't kill the mage first.

Most people who play Evokers can agree that being perma-silenced isn't a fight they'll have any fun with, so the brief respite of immunity will still be appreciated. Those who would rather drop dead than take a damage penalty to their spells have the option of investing highly in Celerity to go first, using a Heron feather, Silent Prayer, or status resistance.
