Didn't want to call you out on it, but now i have to. There is NO WAY you got to level 50 just grinding fates in the small time frames per day you had. Considering the fact that many fates take longer to appear as you get higher in level, You'd most likely get to do the same fate, maybe twice in your 3 hour period at level 37+. The amount they give, compared to the amount you need also proves this. So no, you didn't get to 50 doing it as you did. You most likely would only gain a single level per day doing it in the time frame you allotted yourself

Oh, and Yes, you can make a lot of money socketing materia for people, considering newer players are turned off by crafting, and don't have the ability to create materia themselves most of the time. So you can make a lot of gil with materia.

It's not an epeen contest, its proving you wrong, as you seem to want to place yourself above others.
