4. Raise the price of the philo tome crafting materials. Everyone can easily get philo tomes now. Start raising to cost of those items, if they cost 250 instead of 125 the supply of them would be cut in half and the market wouldn't be flooded with them.

5. Find a way to stop gathering bots. The insane amount of supply for these items has killed the price of everything. Supply is murdering demand right now. It would be a lot harder for crafters to level everything to 50 if shards weren't dirt cheap, as well as materials.

Just some ideas, I'm sure I will think of more later
