This topic has been around for over a year. Players say they have everything for a Legendary except the precursor. Some are still saying that after a year. The most expensive precursor is Dusk at current list price of 778g. Within the wait time for Precursor Crafting to go live, these players could have bought their precursor off the TP. You could do it after 6 months easily if that is one thing that you've been "holding out hope for".
6 months X 30 days = 180 days
778g (dusk) / 180 days = 4.32g per day
4.32g a day is very easy to manage for a player that deserves to have one. Use GW2Stuff overlay and do world bosses. Do temple runs and Arah events. Get into Dungeons and run a few paths a day. Sell everything. If you already have all the gifts for the Legendary, then you should already be failure with these events. I made 150g in the last 7 days doing exactly this. I sold EVERTHING. Look at your collections tab. If you have stuff in there, sell it. If your not selling everything, then you must really not want it.
Legendary weapons are a long term goal for dedicated players. Many players may covet a Legendary weapon, but they are not meant for everyone.
I know the post is from March, but i want to add something to make your math more interesting.
The assumption is totally blown away , since the prices are over double since then.
I was saving money for ZAP, making ~9-10 gold a day from various tasks. Not playing every day, sure, but say 4 or 5 times a week. By the time i made 600 gold, the Zap changed in price from 850g to 1200g. At the moment, the current price of that precursor is exactly 1345 gold. (I got lucky with the mystic toilet, so I am over it)
So yes, new way of precursor acquisition is needed. My hope it that it's not crafting, but scavenger hunting.
Still, I lost hope for that to be added. There is no information for future plans too.
