To be fair, resellers are usually defined as people who manipulate the market to gain money, and LA owners are not needed, since all mobs could exist without LAs, but I wouldn't want them removed either...
Seems to me LA's give MA a one time cash revenue when they sell them but a long term drain of cash and even players.
The players/investors who have made the most money in this game for the most part on LA owners. All that money could have gone to MA and perhaps some of it back to players. One LA owner has claimed to have made millions of dollars. That money was drained from players, many of whom might still be playing had MA owned it and not taken that money from those players and from the game.
There are a bunch of these type of things in game that seem to push players away. Who really wants to pay money simply to move around the game, money which doesn't even go to MA. If it did go to MA at least some of it could be put back into the game. But instead players are being drained money through basic everyday actions like hunting and mining on LA's and even moving around the game. I think the time as long passed where MA needs to cater to it's basic players more and stop thinking of new ways to drain money from them and into "investor" hands as that happens fast enough already.
