ppls are already selling +15 lv.3 weapons(ie. Lacryma Stick and Crimson Mace) at 2b, before all these weapons were vended at 1b. Sellers will adjust for inflation rate, and WP may as well have to raise the limit of vending from 1b to 2.1b.
I hope me discussing about inflation here is okay for VmodMango because thrisbis another inflation topic.
Hmm ... before when a +15 level 3 [holy] weapon sold 1b, WPE rate was 250m. That means to buy one weapon, it was 4K WPE. Now it is 2b and 550m WPE is sold like hot cake, that means now it takes only 3.6k WPE. Note that 550m/k is a selling price, if you are not in hurry, can easily ask for 600m/k and that means it’s only 3.3 WPE which is cheaper.
Take Abusive robe market for example. When WPE price raised, Abusive sellers adjusted prices to inflation to feel that they still got the same ultility. Unfortunately, if WPE sellers do not buy it and normal players can’t afford newly expensive prices of robes, prices would start dropping. Right now someone is selling +13 Abusive robe Vit 6 for 8b and seems like no one is buying it. The only perfect enchant that is in demand and is eligible to adjust price to inflation propertionally is Abusive robe Str 6 which I sold one for 13b at +10.
