Guild Wars 2

I just noticed a peculiar thing about the price of legendary weapons in TP. If you look at their price history in e.g. gw2shinies, you will see that their price peaked at about the end of June and has gone down ever since. What might have caused this phenomenon?

Might be less demand for them as people acquire their own. Not to mention you can make your own precursor which leads to making your own legendary. As people discover they can spend less gold making their own than satisfying their “I want it now” syndrome, prices will inevitably drop. On a side note though, material prices tend to rise, but not enough to make someone decide not to make legendary over spending say 3000 gold for instant satisfaction.
My 2 copper worth of opinion.

Ectos and the t6 mats for gifts of might and magic lost nearly 50% in value since June, which ecuals around 600-700g for each legendary.
If you needed charged lodestones for your legendary, you pay 100g less now compared to june and most precursors also lost 100-200g in value since then.
Just that is around 1000g off your shopping list for mats.

Why did those constantly lost value since june?
AB Farm, new LS chapter and I am not sure when they announced that new legendaries are on hold for the time being. That might have been around that time and might have caused some players, who were hoarding mats in order to craft the new rifle for example, opted to use their mats to craft the old leggie rifle and sell it for a profit. If you check the supply graphs of the leggie weapons, most of them only had less than 10 listings, now most have over 40. So more supply than demand, it seems.

There is an overabundance of legendaries on the TP. Mats are at a low as well.
