EDIT EDIT: Actually this is sort of useful again with the WV build
EDIT: This hasn't really matter since mastery stacking took over. So, I wouldn't really recommend following this at all. I'll leave it up in case folks want to use it as a template for other similar tracking.
This weak aura is heavily inspired by "Arcane Blast Counter"
Fire Mage DPS is heavily reliant on the number of pyroblasts that you can fit in a combustion window. This simple weakaura counts the number of pyroblasts you are able to launch within that window and displays the result.
