This has a pretty easy explanation:
As they introduced more unity ❤ ❤ ❤ ❤, and specifically, Trove-able unity ❤ ❤ ❤ ❤, they gotta force a reduction in currency
They tried to say "its not a conspiracy" and people defended them last time, when they strip'd us from all our White Orbs/CS stuff, but its extremely obvious, and the change was proved unnecesary when a bug made the dungeons take White Orbs again instead of Ascension Orbs ~ the currency change has 0 purpose besides wiping currency
This time is the same, but since they can't wipe it, they'll just massively reduce the access to the dungeon to drain ascension orbs super quick, and then force people to buy shards on F10 and/or unity stuff on trove and probably upcoming bundles
