I'm here to make a suggestion about Skeletoon Keys. Well, as far as I am concerned the lower levels keys are the most hard ones to be acquired, since people usually farm on higher levels (as Darkmoor, etc) and rarely have a chance to get them (the proof is that I got a ton of gold keys and none of others)
So, my suggestion is that we should be able to trade our keys for others, for example:
1 gold key can be traded for 1 stone or 2 wooden keys
1 stone key can be traded for 1 wooden
2 stone keys can be traded for 1 gold key OR 2 wooden
4 wooden keys can be traded for 1 gold key OR 2 stone
Of course these values could change and/or have other ingredients be added in order to complete the trade (like reagents, etc).
Ok first off I do not believe your calculations are correct it should be 2 stone keys for 1 gold or 4 wooden for 1 gold and 2 wooden for 1 stone. Also this isn't a very good idea to be honest. Gold keys are supposed to be hard to get not easy like wooden ones and even stone ones.
Honestly while gold are meant to be harder, as a high level I find I have WAAAAY to many since they drop from a lot of bosses Polaris up. (anyone that has farmed Darkmoor will have entire walls of them) The real grind is getting stone and wood keys from the low level dungeons, perhaps a reverse trade instead? Since if you can get gold you can get wood and stone anyway, I wouldn't even mind if it was simple converting it down instead of increasing the number.
