Guild Wars 2

As the title says, I have thought of a new possible way to obtain precursors without having to rely heavily on luck with the mystic forge or without having to deal with the crazy TP prices.

I know a new way to get them is currently beeing developed by Anet, but I wanted to put this on the table anyway.

-Add a new npc in Lion’s Arch.
-This npc will give to a player the precursor he wants for a certain amount of a new kind of tokens (let’s call them legendary tokens).

The problem now is to figure out how these tokens can be awarded to players whithout making obtaining precursors too hard or too easy.
Here are some ideas I had of how a player should be awarded tokens, taking into account everything (or at least what came to my mind) a Gw2 player may or may not like to do in this game.

1)2 tokens every time a player completes 5 different dungeon paths. This is to avoid things like crazy Cof path 1 farm.
2)players will be awarded 1 token every 10 (15/20?) WvW kills, or every time they help conquering Stonemist Castle in EB, or for a certain amount of towers conquered etc.
3)players will be awarded 1 token every 3-4 sPvP matches they win, or maybe for a certain amounts of kills, points captured etc.
4)Tokens will be tradeable from the golem vendor in Fractals of the Mists for a certain amount of fractals tokens.

I’m not sure these options cover all the possible ways of playing the game players have, but you get the idea.
Also all the numbers I gave are purely hypothetical, and would surely need some balance based on the effort that needs to be put in every single task.

Any thoughts?

They’re already implementing a Scavenger Hunt for pre-cursors.
