The ability for everyone to see how much items are listed for isn't "killing crafting", it's just allowing people to find what markets are or aren't profitable. If a market is profitable, people will continue to join to have a slice of the pie, eventually though enough people will join that market until profits are driven to 0 and it is no longer profitable, this is market efficiency. If a market is unprofitable, then people will leave that market until profits go back up to 0.

If you're trying to craft for an unprofitable market then it's that person who has overflowing stupidity, especially since the marketboard makes it easy for them to check the current market.

If you aren't making profit in one market, move to another. Ideally, things will have narrow profit margins.

Blind bidding is bad because it doesn't allow people to see what the actual market looks like, and no one can make proper decisions and it would hurt market efficiency and cause large price gaps.

A lot of these threads seem to be made by people who feel they are entitled to large profit margins.
