In all honesty. As the title states. Buying from another market. Fine. But cross world trading needs to go and stay gone. There was a rising problem in market prices on my server some time after they introduced this. IT has only gotten worse since then and it's not fun. And what's more is, it promotes third party users/botters to just do it more than they already did and spread their "wares" to other servers where they drive the prices into the dirt because they simply don't care. They themselves aren't crafting or gathering the mats. Their bots are.
Example. Currently on my server there is a person i've been following and monitoring since ShB. He currently has TEN sets of crafter necklaces alone up on the board. What's more is he undercut the previous person by 9k just to sell his wares. He is not from my server. I have looked his toon up. He does have one made on here, but it is a level 1. And the necklaces aren't eh only market. He does this on every possible post he can. Now. Take the time to think about gathering the mats, time to craft, time to do other parts of the game. I can't get the mats fast enough on my own to do this. Let alone constantly sit around making and crafting while also gathering said mats.
To put it more into perspective. I did happen to find what server his main was on after searching the worlds on my DC. Upon going to check on him. He's ALWAYS online, locked away in a private room. No matter what time of day I happen to log in and go check (though admittedly it has been harder to do so since the congestion. but around 11pm EST to around 2pm i've seen this activity whenever I can get a slow congestion pop to move over and check). Now like I said. I've noticed this activity since ShB. It's not just a new occurrence. Cross World Trading is a nightmare for just this sort of botting action. And it's terrible to try and go against because you just can't unless you yourself bot. It needs to go. Or lock CWT behind needing to be max level for the current expansion. To force out these people who wouldn't otherwise put the time in to have to or not be able to do this sort of thing. It breaks down to third party usage imo at the end of the day, but at least CWT would help somewhat if it was adjusted. (And by saying Third Party usage is an issue, it can even be seen currently with people avoiding the AFK timer by using the third party Bard musical apps to hide away in homes and play music with it to avoid being kicked and skip queue'ing all together).
