There should be a monthly event similar to the mega stash, with high reward cosmetics attached. Some people will complain, but not everything is for everyone. I did about 50% of the last tall tale, but others loved it, and that's great for them.
For example: For a week starting on May 1, Molten Sands is now a super fort, containing 5 ashen athenas, plus ashen captains chests, ashen skulls, etc. It's marked by a large red skull in the sky. Then, you have various commendations with ship parts or clothing items attached. Complete 5 molten sands, get the sails. Turn in 100 ashen athenas, get a hat. Turn in 50 stolen ashen athenas, get a title. Yes, some of those might seem like a high number, but it should be. Not everyone should get every commendation just for participating. I remember the old Reaper's Run voyages that had to be completed with the Reaper's Mark up. That was difficult, and the rewards were worth it.
The last week has been phenomenal for interactions, the best that I can remember since FotD first came out. We need more of these events. For me, I'm not concerned about "inflation". I have 400 million in gold that I'll never spend. I'm sure there are many players that are in a similar situation.
