Extend a number of the features from the Crystal Cove event into the 3 Barrel Cove wilderness and quests including:
1) Copper/Silver/Gold doubloon drops - 3BC wilderness
2) Map pieces - 3BC wilderness
3) Treasure Compass - 3BC wilderness
4) Dragonshards - 3BC quests : Only upon completion you get a "pirate booty" bag that you can trade in to a 3BC merchant for 5(norm), 10(hard), 15(elite) dragonshards.
5) The pirate hat & upgrade barter box
This would give players the incentive to purchase and run 3 Barrel Cove to be able to create customized pirate headgear (with the release of the challenges the ability to upgrade kobold miner impacting effects on pirate headgear would be a big boon!). The droprate on Dragonshards is low enough as to make 3BC quest farming for shards intended for use in upgrading epic items prohibitive but yet be viable for somebody who wants to upgrade a hat with some dedication/work.
What would not be included in 3BC is:
1) Any Crystal Cove gem drops required specifically for Crystal Cove item purchases.
2) The CC Item purchase/upgrade barter box
3) Kobold Miner requisition drops
4) Named treasure maps for random chest loot
Don't need to add an easy button for people to farm CC regular/epic items and consumables outside of the event.
