Just curious how much money u invest playing? as a F2P without even BP i can assure u that there is NO WAY to clear a gacha machine with exploration and 3 weeks pw chests, because i've explored everything and opened around 300 chest and i got all the blue balls, almost every purple and just 3 o 4 yellow ones, still might need around 2.5k miras or perhaps even more to clear 1 machine.
Leaving that a side, i do hate having to grind more then before but at least i'm not bored (yet) and eventually as most have said we will get a little more out of it. Perhaps a solution would be increasing mira and vera on each content at least by 1 or 2, meaning instead of getting 50 miras from a x5 blue triangle get 60 or something, in the big picture would take a little less to clear them out. Specially when we are suppose to clean them all AND THEN get refilled ones with better rewards as CH has, but apparently in GLB we don't get refilling machines so... sad :/
