Fate, Ice B, and Vex Mytho infusion to Y3, and I and [i]many others[/i] would never want for anything from the game again...ever.
They [i]have to[/i] bring them back, err, up...to Y3, they just have to. Certainly before Destiny moves on to D2. I mean, Gjall and Thorn are coming back.
I hope they sneak all three in, from Xur. Xur would be king of Destiny again...he'd be Y1 pre-anything-nerf golden!
