But right now in sandstorm elementals get double penalty. They hit for less damage, because sandstorm acts like a shield instead which elementals ignore on self, but elemental pets themselves get hit in sandstorm for full amount. So your opponent takes less damage, while you take full damage if you are elemental.
They really need to rethink the elemental racial. Why make all elemental plantlife require sunlight, but make them ignore it while sandstorm completely butchers elementals (and yes tehre are elementals that cast sandstorm)
