After watching Bungie handle a 17k+ post on this topic by ignoring it and continuing to see other posts like it, here is my prediction for the solstice this year!
Bungie: “Now we are giving the players what they want, a way to grind out the solstice gear from previous years but now as ornaments!”
Most Guardians: “We already earned those sets over countless hours of grinding and don’t want to earn them again. We told you when you did this with Iron Banner that it was a big fuck you to the community. Why do you do this to us Bungie?”
Community Manager Response to inevitable 10k+ post: “Players asked for old armor to be made into ornaments and the dev team did that. I will pass along this feedback that players are unhappy to re-earn stuff they earned before.”
Also, less of a prediction, more just exactly how they did IB.
