Opinion 1) plot devices should not be disguised as class features or vice versa.

Opinion 2) The general theme and feel of the game that the GM and other players are going for should dictate what options are available as class features to facilitated that theme. Trying to do it the other way around leads to madness and unfulfilling game play.

Opinion 3) spells cover way too much ground and need a retool. You can't have something like a small localized effect and something that could potentially shatter the world on the same scale and it make any sense.
