We need more ways to make gold in this game.

I made 200k from doing quest lol too many ppl fate grinding instead of doing quest even tho i already had 2 mil gil from 1.0 i made about 2ook lvling my SCH 1-50 cause i always took the tin silver or gold pieces. Those things should be enough to stimulate any server.

Those are one-offs. The quests can be only done once, and after majority of the players have finished the quests available in the game, the economy will start to stagnate (more gil going out of the economy because of repairs, teleporting etc.). As mentioned several times, AH isn't generating gil, it's removing it, so "leveling crafting classes" or whatever isn't a solution.
