I think people forget that as soon as TTK drops that the "Sleeper Stimulant" or "Gally replacement" won't be immediately available and that the Gally that Xur has no sold will not be obsolete right from the start. Sure wolfpack rounds is getting nerfed, but like most MMORPG mechanics extra damage is better than no damage, also very happy Xur sold it so that the last stretch of year will be a breeze for all.
