I start with the problem. I know plenty of people who would like to buy gold/tormented weapons for real money and they are pritty much forced to do that cause they play GvG only, that is they take part in guild wars But they also want to have shiny armor and weapons. Right now there are 3 options: farm in PvE, farm in HA and buy gold for real money. I know ppl who don't have PvE chars and HA is nothing compared to GvG.
So I propose to introduce GvG chests for winning teams. The loot should consist of perfect weapons customized to the player and armor pieces, meaning no impact on PvE economy. The skins of weapons and armor should be scaled to both guild ranks, that is if both guilds in top 100 and you win you have a chance to get a piece of FoW armor or a tormented weapon. I reckon it's quite fair to reward those people who spent years playing GvG.
It would impact the pve market as there would be no reason to pay a pver money if you can just get something as reward for pvp.So demands drop and so does its price.
