Further testing on dummies also shows that a Thunder III thundercloud proc does more damage than a Thunder thundercloud proc. In my case, Thunder III does around ~750 dmg, whereas Thunder only does ~500 dmg.

That's good information - I'll have to do tests myself, but if it's true I'll have to change my setup.

I cast Thunder III cause it looks better.

100% agree. I'd like a Master Spark BM skill... very, very disappointed there's none currently.
