Community data says otherwise. (consults spreadsheet) Let’s see … I haven’t updated my data analysis in a while but across 745 Gem Dragon Eggs crafted by 78 different users, the distribution per dragon is 107-138 (vs. mean value = 124), which is actually a pretty even spread.
But yes, the system feels bad and everybody agrees on this – heck, even the devs have been told this, albeit they obviously exist on the other side of the communications curtain so we don’t know what kinds of conversations occur on the design side or what specific plans to improve it might be announced soon.
