It’s a pretty long journey to get to the end of the season… journey. Unfortunately for players that have already gotten there, the rewards cache at the end isn’t dropping the items advertised!
The final chest reward at the end of the Season 5 journey is supposed to reward a guaranteed two Greater Affix item level 925 Ancestral legendary item. However, as many players have noted, the Greater Affixes, aka the big draw of the reward, seem to have gone missing!
There are many more reports of this from other players as well. And so it doesn’t appear to be a limited issue this time around. Hopefully Blizzard can get to it in the next batch of hotfixes. Especially since the last two were fairly quick to come out, which you can find here and here.
