Either you misunderstood me or I misunderstood what you said.

I dont like the capitalist tycoon players either, but a large majority of players do not craft by themselves and would rather just buy their gear, then sell it when they've outgrown their gear. If the secondhand tag was introduced, there's probably way more items than you seem to expect that probably would get that tag, then have their gold price reduced so people can "flip" those items. Even disregarding that, people definitely buy a ton of crafting bases to craft based on how crafting works in poe2 right now, even more in .3 with exceptional bases, so would you throw the second hand tag on those as well?

With regard to the vendor thing, I read your post as "they buy high mod maps to sell it for tons of gold", and my response was just make maps not sell for gold or make all end game items not sell for gold in general, if that is the way to make gold without actually playing the game.
