To do certain upgrades on Guild Halls you need Heavy Supply Bags. They no longer drop AT ALL in wvw because those maps were taken out and there are not lvl 80 centaurs in the new wvw map or in PVE. Now there is only 300 Heavy Supply bags in existence on the tp and they went from 30 silver all the way to now 10 gold a piece. How are guild halls supposed to Upgrade if the items they need like the Heavy supply bag. They don’t drop in wvw or pve XD . The only way now to get them is the super limited tp ones that are way over prices or a chance, a small chance of a possible drop from a krytan pvp track. This is WRONG. Each Guild hall will need 150 in all to upgrade certain things and only 300 exist. This is a mistake. Either anet needs to add lvl 80 centaurs somewhere or they need to make a mystic forge recipe that makes them , or they need to change the guild upgrade item to something like a heavy loot bag and not a heavy supply bag. THIS is a guild hall emergency of epic porportions!
