Sand magic had.... Really great, and easy potential to be used with other trees for devastating, easy to landcombos that could have been used to wreck you in. The increased RPP costs, while perhaps a bit much at certain areas, helps in making people either fully commit to the gimmick, or pick and choose what they want out of sand.

The sand root in particular was the big culprit, due to it being a root AoE that moves with you with a decent duration.

Not sure about metal though. Frankly, didn't have a chance to fight against one.
