What if you could spend gold on single server instance cosmetics above and beyond what's available to own?
EXAMPLES
Ghost Flames
Ghostly green glowing flames that dance and burn along the edges.
Sails (They whip and trail in strong wind) 750 gold
Hulls (A virtual conflagration at the waterline) 1000 gold
Cannons (including trailing, fiery arcs) 500 gold
Personal Pirate (Your basic green burning pirate from hell) 500 gold.
Pall of the Dead
A horrid look of rot, death and despair actually shrouded in inky, billowing darkness. Downright skeletal.
Sails (Basically skellie ship with extra shadow) 750 gold
Hulls (Basically skellie ship with extra shadow) 1000 gold
Cannons (including trailing necrotic arcs upon firing) 500 gold
Personal Pirate (zombie flesh, missing teeth, pupiless eyes, etc.) 500 gold
The Drowned
Seaweed and bloat. Fish parts and tentacles, etc.
Celestial Flare
Bright motes of energy and light. Sparkly and fun.
The Devil's Flames
Burning red of lava and flames. Don't worry. They're not hot.
This idea stemmed from another thread wanting to give value to loot, but in my opinion it's a good one all by itself. So many people have vast hordes of gold and nothing to spend it on. This would provide a fun, worthwhile gain and possibly give incentive to care about loot again.
To be clear, this kind of bling is over and above anything you could buy as clothing and regular ship cosmetics. Real exciting visuals.
