But bug reports of Every Light's side-effect have not been confirmed or acknowledged yet.
Since several updates have passed since then, we can only workaround the issue, and that is to use Death Ward to avoid it. Perhaps the devs see it as WAI because the effect can be overused, so DW is required to offset a party with a Mystic throwing it around. Yet, a ninja has no problem in performing a similar ability.
Please send bug reports to the devs--simply talking about it in the forums is no assurance that the matter will gain attention.
