If Bungie releases Gjall they are confirmed for the most hasty and unthinking developers. Gjall can't be as good as in D1, if it is they will trigger a wave of complaints because it will trigger the same response as the nerf of Whisper. Also part of the legend of Gjall was people overseeing it with Xür's appearance, leaving most players looking for it because they missed it. Now you just pop your weekly Xür engram and there you go, Gjall day 1. There's no point in releaskng it just for hype. Ohwait they will use it just to hype their otherwise useless 10€ season.
