Any good WindBreaker builds?

If you're training at FoG, you're pushing things into the corner and spamming Storm Breath, not Arrow Rain. If you can pin pomegranate into a corner with Storm Breath, just use Storm Breath. It has further range than Arrow Rain and won't aggro things behind you, why bother wasting time and risk taking pomegranate loads more damage that could potentially kill you by closing even more distance? The places to train with Arrow Rain, Storm Breath is probably the last thing you want to do there.

Thats for FoG though which is totally deserted. The minidungeon is not so harsh though, you could push the middle lane monsters and rain both upper and lower lanes along with it.
