Guild Wars 2

Are precursor’s so stupidly over priced

And why have you still not added precursor crafting in to the game it was supposed to be last year anet

Supply and demand.

They haven’t added it yet because they need to make it balanced.
Making them cost too much to craft will make people buy them.
Making them cost too little and people that have bought or are selling Precursors will cause an uproar.

And indeed it was PLANNED for last year, but on the other hand they were also quite clear rather long before last year was over that it would most likely be pushed to this year.

I would say a safe bet would be the Feature Only patch coming after the Finale of Season 1.
