OLDPIPE The problem is that JB's new annoying format gives (at least for me) so many gems that everything else goes second.
I've earned over 1'200 gems since the JB change. Some was from the achievements and some from the event, but I didn't keep tabs. Either way, those five gems and sometimes 50 gems really add up after at few hundred chests.
So... Yeah, I'll keep focus on JB. Probably gonna do some global too, but I wont prioritize it as I usually do.
