They gave out free t4 materia and made t3 and t4 much much easier to get, meaning the prices of them tanked. also they lowered the HQ rewards for repeatable leaves and greatly increased the drop rate of farmable crafting loot (skins, webs etc.) sure they added a static amount of gil from dungeons.. but they killed off several trade markets.

i just spent 250-300k leveling carpenter to 50 to get byregot's blessing to HQ gear to use for spirit bonding for materia to sell and i paid for it by farming mobs, now my farming source is gone, as well as the materia.
