New Character slots. No money no slot
It’s not really that bad, I think the price is okay, currently it’s only about 25 gold per slot, which isn’t all that hard to get, one average exotic drop or a few hours in CoF, or selling about 120 ectoplasms which are also easy to get with all of the rares being handed out at every turn. The recent Super Adventure Box was also a very good way to make money, I managed to squeeze about 100 gold out of it. If you’re out of character slots that means you already have 5 characters that you play, surely you can find a way to use them to get some gold.
