Any good WindBreaker builds?

Windbreakers will do excellently in Truckers, I imagine. Same goes for FoG, Windraiders, etc. The combination of Storm Breath and Arrow Rain is very similar to how PA DrKs use Rush and Fury, albeit with more care not to take large amounts of damage. Typhons I'd imagine are extremely fast for WBs.

Storm Breath + Arrow Rain = fail, I'm pretty sure.

Push range seems to be .x not .range, so it's 300, not 150. At least, that's what I've discerned from the videos I've seen, though in that case, I have no idea what .range would mean. Correct me if I'm wrong, Isaac.

Well, in either case, one of the two is not defined as doing something, but it's either 300 push or monster position +150 which is complete fail for Arrow Rain.
