Everything I read about is crafting a precursor.
Enough with it!
Get so many of that material, so many of that other one. It feels like a bad Japanese game.
So instead of forcing me buying stuff (T6 craft) or running a thousand world bosses, make it so I have interaction with Tyrian people. Make me use my brain, make me travel accross Tyria, make it take time so I can enjoy getting that precursor, but be careful: don’t make it boring or dull, I don’t want another Trahearne story. Use random wisely, make me go on a quest for once. Also, make it hard. Not huge-life hard, but i-have-to-use-my-brain hard. Make this part a complete adventure. See Indiana Jones (not the last movie, but the others, or even the Indiana Jones Atlantis game), make it like that. This quest should take roughly 20 hours and should not be doable in under 5 if you skip everything and kill everything on the first try with zerker. Also, it should be properly scaled if people do it together and most of all, it has to be exploit-proof.
If you’ve already finished implementing the recipes, just scrap them and rethink. Crafting is the way of the lazy both as developer and player.
TL;DR: Make a new game to get the precursor. Seriously.
