I had made a long post explaining it, but it seems it got removed by the admins. I'll keep this short and sweet, to see if it lives any longer.
FW is sorely in need of some trade gold injection. Casher's cannot get gold through any means other than the mega expensive 20 leaves for a single merc statue, which puts the leaf for gold exchange rate at a low point that I've not seen in my 5 years in the game.
Casher's can't get gold, farmers can't get gold (because the cashers don't have gold to spend to buy their stuff). Just 4D will see someone make the top 500 wealth list on Lionheart, and half of those characters on that list don't even play any more. There's a handful of characters with a significant amount of gold, but for the rest, they're only managing or short.
We need a merc pack sale, or orbs with gold in them, or something. Advancing characters costs gold, and the end game instances all demand for fairly mature well specced characters. If the majority can't get gold, then the game will die.
Prices of goods are in near total free-fall on Lionheart server, but the costs required to advance a character hasn't changed. Re-IDs, Fusion Agents, mastery/resists, rune making, relic spirit making, anima training (beyond a certain point) all cost gold, gold that is increasingly hard to come by.
This is frustrating those players who wish to participate in end-game instances, but cannot, due to lack of ways to obtain gold.
