Sorry, I disagree with you Merry Munchkin, But this is something to get upset about. People took there own time here and because of that they gained xp, that xp was used to make Enchanted items. Those items were fine until suddenly they weren't. So with the team that runs this changing things over night, Basically its our server and no matter what input or time you put into this server you don't matter here. I have seen this happen over and over and over again. This even pushed me out of the server here. So yea it is something to be upset about....
Yes, I can see your point -- up to a point. No one should be blindsided by an unpleasant surprise. However, when you put in the time to play this game and earn xp for your character, presumably you were doing so because you enjoyed the game, had fun playing with other people, and would have spent this time playing regardless of whether you had an option to "cash out" some xp later for crafting purposes. The fact that you chose to use xp for crafting purposes doesn't make all that playing time somehow disappear, or that your enjoyment of that time spent playing is somehow diminished.
XP is a consequence of play, which everyone presumably is doing here voluntarily to pass the time and have fun. The fact that what you chose to "buy" with that xp in crafting is now diminished in your eyes does not make the prior experience of playing and accumulating that xp somehow retroactively unenjoyable.
However, I do recognize that some players may have chosen not to cash out their xp in crafting if they had known what the items would have become, and as a consequence they are potentially further behind in their character level progression than they might have otherwise been. The solution for this is simple -- let players trade in their crafted items (which presumably they would not have chosen to make in the first place), and provide them an xp "refund" of some sort.
Personally, though, I think the concept of a refund should be tempered by the fact that there is not an xp or gold shortage in the game -- the game generates spawn and loot on an infinite basis. Kill all you want, it will make more. The only resource the players actually have to "spend" is their time, which no one can replace anyway.
Consequently, my previous position holds -- this is not anything to break out the torches and pitchforks over. To the extent that players want recompense for xp they would not have voluntarily cashed out, some sort of corrective action should be relatively easy to do.
