I will also be waiting before buying. I really think the best way is to wait till the end of Destiny 2, buy the full game with the last dlc and get all the content for $60 and not have to deal with your favorite gear being destroyed by Bungie.
The PvP gear balance not being separate always baffled me. It just seems to be the best solution. The whole making weapons feel the same argument holds no water with me.
