This is me recycling a reply I made. Yep.
Rare understandably can't add any PVP milestones as it would make this sandbox game a spawncamp every crew you see death match.
However... There are a lot of unused potential trinkets.
The seadog tavern is a beatiful place. And it has a lot of paintings in it that can be rewarded for past glorious deeds. This would be a great way to reward some arena lovers.
Level 5 seadogs: Lesedi on the helm painting. (Inside and outside the tavern in Amaranta's lair)
Level 10 seadogs: Seadogs building the parkour course painting (inside the tavern)
Level 25 seadogs: Lesedi and DeMarco with a chest painting (inside the tavern)
Level 50 seadogs: The Good Boy galleon painting (outside the tavern)
Iron Sea Dog: Ramsey holding ancient chains painting. (Inside the tavern)
Glorious Sea Dog: DeMarco announcing the opening of arena painting. (Inside and outside the tavern in Amaranta's lair)
Triumphant Sea Dog: Ramsey, The Noble Pirate Lord in his flesh standing in front of his ship crest painting. (Inside the tavern)
These are all already made assets and just throwing them into the trash bin doesn't seem right.
I think this is a great way to have a use for them.
