I have some tips on how to make gils. Since gathering and crafting classes are pretty useless for making profit (on my server it is).
Here is how to make profit without knocking on market board.
1. Treasure Hunting Maps. Very important that you have gathering classes at 50 to gather pesitskin maps only or have Gil to buy them. Start or join the party through party finder or with your friends. Must fill up to 8 and each one have to have one or more pesitskin maps.
With that, you make 13K+ daily. 70K+ per week. Don't bother selling maps unless price is over 15K.
2. Doing dungeons. You may barely make Gil and at same time repair remove that profit you made. So better grind like a hell. AK gives 3K Gil by clear all mobs.
That's all I know for now. Keep in mind that is possible in 2.2 will bring gathering and crafting classes profit again.
Got any better idea? Discuss
