Unless of course you wanted an easy path to more oaknots, to get sealants, for you main character, to create more gear for less to control the MB.
But to that, I do say, more power to them.

And honestly, if people want to spend their day jumping alts to 'control' the mb... good for them.
I'll still craft my stuff. Post it, and gain.

They can buy it all out or sell a lot at a low price to..... remove profit from anyone... for a time.
I'll buy that cheap stuff, and wait till they have expended their desire to bottom a market, and then I'll sell it again. At a Higher price.

In the end, it is just a game.
And for some, its not the game, but the game within the game that they decided is important to them. IE, being an MB Baron/ess. To cater to those people is the wrong direction to take a game.

The only business models that survive catering to the 1% are because those 1% supply more income than the other 99%.
This game is not that business model.
