Its happened :/ - resorted to new character for Gil.

[Ryios]

Somethings that could be added to offset this:

Free repair at end of successful dungeon/primal/leve. That way the 200-1000gil reward is not immediately wasted to get your gear repaired.
Higher gil rewards for dungeons/primals/leves.
Higher gil drops off npc type mobs.
Random chests in the world that drop Allagan pieces.

There are plenty of things to do to inject some ways to get more money than you are losing. This is not about a person becoming wealthy on the server (which happens at another's expense).

Or Solution B

Let us buy alagan pieces with GC Seals

50 seals = 1 bronze piece
250 seals = 1 silver piece
1250 seals = 1 gold piece

So If I fate grind all night and net 20,000 GC seals that would be 16 gold pieces worth 40,000 Gil and I'd probably repair twice for around 5k total at a net profit of 35,000 gil.
