I’m with @Graylady on the poor JB rewards. I finally completed the Prestigious achievement today, so have played well over 100 chests, and I think I may have only had 5 gems once in all those chests, and hardly any chevrons too 😕.
For me, it’s been just materials/xp with the +1250 capacity captain thrown in since last weeks update on a fairly regular basis.
Now that the achievement is complete, I’m not touching the JB for the rest of this event, unless I really, really have to.
And this thread is malfunctioning..... 🤦♀️
