Spell Balance Suggestions

[Cotillion]

This is less of an important request, but I believe that pandemonium drive should be moved to be more in line with other mythic toggles. It does change the aesthetic of a lot of spells, and even fundamentally change a few nature spells, however, as it stands it's mostly a detriment as a hidden comparatively with glorious inferno, titan of light and other such mythic tier hiddens.

Would it be possible to remove the negative DR aspect, and perhaps tweak it's power modifier if a flat ten like the other two is considered too egregious?
