Guild Wars 2

Blue Mystic Forge Stones remain as they currently do.

Add:
Green Mystic Forge Stone

This item acts as a place holder for random recipes of armors, weapons, runes, sigils and dyes. It grants a 30% increased chance of promotion in rarity increasing this chance to 50%.

Green Mystic Forge stones drop from Daily, Quests, Map Completion, Lockboxes and 500 AP achievement chests. Blue Mystic Forge Stones can be upgraded to Green using Blue, Green and Yellow Essence of Luck in the mystic forge.

Yellow Mystic Forge Stone

This items does what a Green Mystic Forge Stone does except it yields a guaranteed chance of a promotion in rarity.

Yellow Mystic Forge stones drop from Monthly, Quests, Map Completion, Lockboxes and 1,000 AP achievement chests. Green Mystic Forge Stones can be upgraded to Yellow using Yellow, Orange and Purple Essence of Luck in the mystic forge.

Orange Mystic Forge Stone

This item does what the Yellow Mystic Forge Stone does except it yields a higher chance at yielding a precusor.

Orange Mystic Forge Stone drop from Living Story events, 5,000 AP achievement chests, and purchases with a high amount of Laurels.

Purple Mystic Forge Stone

This item does what the Orange Mystic Forge Stone does except it yields a greater chance at yielding both a precusor and ascended gear.

Purple Mystic Forge Stone drops from 10,000 AP achievement chests, the culmination of Living Story Events (if all requirements are met), and special events determined by ArenaNet.

I like the idea for the Green MFS, but I think the Yellow and above stones might be too excessive.

Yeah, just looks like you are looking for a way to inject more precursors into the economy.

Sounds like someone has a had a lot of bad luck at the MF

Hahaha yes indeed!

Actually, while writing this my laughter turned to imminent fear once I realized the true potential of this idea. I can smell a potential P2W cashcow from miles away, which is exactly what these stones will become if implemented.
