What the fuck? They didn't tell us this shit when they introduced Exotic Shards to begin with? I spent 3 Shards maxing out my "original" exotics since the new mechanic went live. Looks like they were completely wasted, since I could have just saved them to "reset/upgrade" the gun since there's zero return on investment on the original used shard.
What the fuck are they thinking?
I agree that they should have waited until the first day of the expansion going live to offer these shards. Or at least make sure everyone understands how this mechanic works before releasing it into the wild.
