Idea: XP for crafting/synergy!

Players get XP/LP for every successful synthesis, 10 points, 20 if you HQ, 50 if you skill-up, and XP/LP equal to the guild points for any items turned in.

For Synergy, the Leader gets 20 per successful synth, 40 for HQ, 100 for skill-up, and the rest of the PT in Synergy range get 10, 20, and 50 respectively.

Maybe that will get people to make items again and the AH might get stocked.
