Four: IDOCers are 'salvage men'. If they didn't pick up what falls it would simply decay and be lost forever. Would that be better?
Actually yes, I personally think that it would be better for Ultima Online.
Why ?
Because the game can live only as long as players find reasons to do things in the game.
By salvaging items at IDOCs, players make stocks or items, resources, BODs, blah blah.
That means they do not need to have reasons to play the game in order to get those items because, simply, they already got stocks of them through IDOCs.
So, players start loosing interest in the game and the game ends up losing.
IDOCs create an abundance of items on the market when there is a fewer number of buyers because of a reduction of the number of players or of players who actually need those items. Prices become marginal and make it for even become more difficult for the random new or returning player to come back or anew to the game.
Think of it like a brand new Shard that was just created today. There is no stock of resources, no stock of artifacts, nothing at all. Everything need to be worked for, hunted for. A LOT of playing opportunities for all those players playing that brand new shard where there is nothing. A whole new market that needs to be built up.
Now, IDOCs are the exact opposing pole of the above. They take away reasons for players to play the game because they hand out stocks of items be them resources or else, on a silver platter and often, these items are so many and abundant that they overlast whatever time the player may be playing Ultima Online.
Nope, to my opinion IDOCs work against the better being of UO and they should never be.
Houses for unpaid accounts should just disappear with all of their contents and be taken out from the game, entirely.
If it was like this, it is my opinion that then, the remaining players could enjoy a more lively game play and more lively economy.
