I added in some research I have done in BQL to the heroic strat update. Very briefly, the bite goes to the most damage, not the highest threat (a lot of the time, these are the same people, however)
Work seems to have settled down a smidge and I should be popping up the rest of my heroic strats in the next day or two, I hope. Remember, if you have anything to add to them, pop a comment in and let me know!!
