This also lowers Shard Shop income for veteran accounts from Guild Currency.
Currently, if you have all the toons from that shop, you typically buy the 5 shards of Cassian U wing for 95 SS currency. That is higher than 5 character shard for 75 Currency.
After change, you get 10 character shards for 150 currency, which is a better deal than the ship. But prices doubled. So it is loss of ~18% from excess Cantina currency converting to shard shop converting to gear.
Again, small, but the last thing we need is throttling down of gear acquisition.
