The problem is this;

I hit lvl 50 on my WHM 5 days ago.
I had 185K GIL when I hit 50
I have done nothing but run dungeons since hitting 50 and I am now down to 140k GIL just from repairing my gear
I havn't bought anything since hitting 50.
You don't make enuff GIL to cover the costs of repairs to continue doing what you want, which for me, is farming dungeons.
At some point I am going to have to stop doing what I want and will be forced to craft/gather just so I can afford the repair costs of running dungeons.
Dungeons should drop enough gil to at least cover the costs of repairing gear
