Guild Wars 2

What if any benefit is there to the Mystic Forge Satchel Recipes for armor?

I don’t get it, why waste 50 mystic coins for armor recipes you already have?

Isn’t the cost the same for making the individual pieces vs. a full set?

Its the convenience you get instead of individually making each armor piece in a set. In other words, they aren’t worth it at the current price of mystic coins.
