Right this every minute, many of you are acquiring Black Spindle. Surprise!
Wouldn't you know it, there is a bug that is enabling some of these weapons to drop at 310 - that's 20 points higher than intended. In the near future, we'll be releasing an update that will adjust the Black Spindle to match the attack rating for other Year Two Exotics.
It has also come to our attention that you are using this new acquisition to Infuse your other weapons. Good on you. Have fun with that. None of those weapons will be affected by this change - only the Spindle.
What about those of us that actually got the Spindle at lv300 and actually grinded in the raid etc to get a good special to infuse to it? Worked my ass off to get mine to 308 only to have it nerfed to 288. Thanks for the kick in the balls Bungie.
