I don't know why they'd blow up Vale, only that they'd need tons of dust. You did mention revenge as Cinder's motivation, perhaps she's very, VERY pissed.

If they were to take out infrastacture, a force could easily overtake Vale. White Fang for example, or anyone else. Even an uncontrolled Grimm horde would be a good distraction if another objective would be at hand.

Plus, hitting the championship would mean no hunters in the future. No matter what their target, if it doesn't sit right with the population, a few generations less of hunters is an advantage. Not saying they will succeed that early, but a sheme's a sheme.
