Wat happened? 
There was some misunderstanding in the balance team. Bow damage was supposed to get lowered by 2 for all bows but in the same turn giving them back the old heirloom bonuses, where
masterwork and
strong bows get +2 damage,
fine bows get +1 damage. Instead of doing that, only the damage increase for looming has been put in the patch without decreasing base damage by 2, which happened through an oversight.
Has already been pointed out in the announcement thread but right now everybody is too busy raging instead of actually reading whats going on
