i think large artifacts were about 10-15k emblems and lesser/mondain artifacts were about 2-3k each, so were all the stealables.
around copper/bronze runics made in a metal were worth about 600, golden about 1000
so you'd be looking at 35,000 emblems for a golden hammer's trash, 24k emblems from copper/bronze hammer. no doubt gauntlet artifacts should have been worth more, but i dont think the others should be worth less, you need like 1.5 million emblems or something like that for a heritage token
it even works out better for the people who are burning lower hammers (the lower players), i really dont think there's anything wrong with it as long as you make it clear it will be a long time between events so people shouldn't rush to repopulate their stocks
i mean fair enough it's not reducing the number of items in the game, but it does loads of other good stuff, it encourages people to put down houses, to plan long term and invest in stuff, to be more willing to burn runics (making a better market for farming runics), moves wealth to lower players, gives items people want, gives items people need, makes it worth farming minor artifacts and mondain artifacts, makes those items sellable... there's LOADS
people will ALWAYS find something worth keeping, even if you remove runics from the list, they'll find something else anyway. or even if they're worth less, they'll still keep them for the lower amount. it would not solve the problem.
removing craftables from being something worth keeping for CUB would end up being completely arbitrary, and will just piss people off and serve no purpose, other than making less emblems this cub. my houses would just be full of single bods or something if not runic scrap
