ok, I brought some of these suggestions to Earendil already... but I want to bring them to the general public as well to maybe get some community feedback.
firstly... the link from WoW Vendetta doesnt work... I think that fixing it might bring in some people.
now, since I dont know about others, but I have been having much trouble finding hidden vendors, namely... I havent been able to find any I suggest a different system for custom eq...
place the custom eq vendors as follows... 1 in alliance town, 1 in horde, and 1 in neutral... switch their locations every week just to mix it up a bit.
on the custom vendors that are in the diff towns, instead of just buying stuff with gold, charge custom currency, for example for some item charge a combination of gold, maybe arcane tomes and t6 tokens... or maybe a custom repeatable quest that awards currency for custom vendors... another currency could be a quest that awards currency for a certain amount of a random item... something you cant farm before starting the quest, and something that will change everytime you do the quest again...
i had more ideas, but i think this is enough for now... any input will be appreciated
