Instead of precursors they should give items that let you go on a terribly hard quest chain that could possible even involve going into extra hard dungeons which would actually feel like a legendary archievment to finish. This Quest should reward the precursor.
Like “Broken Blade of Dusk”
Throwing money into the TC or items into the forge feels als legendary as getting rid of athlete’s foot.
Even the other stuff isn’t legendary, just grinding, a lot.
