I created a post myself but late. This is what the TWAB should have read: All masterworked weapons will continue to make orbs as they always have, but if you chose to use an Exotic without a catalyst you can choose to use an armor mod of that damage type to make orbs with that particular Exotic. That's all they had to do. Guess we'll just have to wait and see unless they realize beforehand how badly they screwed up.
