For starters if Anet needs to rely on precursor carrots on a stick to get people to participate in their events then they need to seriously look at the overall value and appeal of their events.
And sorry, but 400-500 gold for a greatsword precursor on the trading post is a little hard to swallow. Sure there are precursors I don’t use that I can buy for 100-200 gold, but I don’t use them so why would I make them? lol sorry I have no use for a legendary weapon I don’t use.
A precursor vendor makes the legendary achievable for EVERYONE that plays this game. Not just the select few that can buy gems until they max out their credit cards or spend every waking hour in game grinding because they have nothing else to do.
