To start with the obvious, in-game Resources are intended to reward those who put in the time earning them while simultaneously putting a realistic limit on how quickly they can be earned and thus how quickly they can be spent. The Legendary Shard economy has become functionally impossible to balance as it is an uncapped currency that has seen multiple instances of infinite Resource exploits over the years. Any attempt to raise Shard costs for Focusing or Resource purchases/exchanges to account for those that exploited their way to six/seven digits worth of Shards would effectively punish long time players who didn’t use the exploits while also running the risk of locking new players out of the ability to use these services. There are a number of other Resources that players already have to spend alongside Shards to Focus/Purchase items; Resources that do not suffer from the same problems as Shards because they have historically had hard caps that have prevented a select few from exploiting their way to near-inexhaustible stores. So just remove the problematic Resource. Easy. (΄◉◞౪◟◉｀)
