Please make Treasure Maps more robust and remove the 18 hour lockout...

I really enjoy this piece of content, but just like so much in this game, I can only do one a day because of lockouts. If they were more robust they could be a piece of content to do whenever I'm bored, which is often given that the game is made to entertain for a few hours a day and no more.

Take most of the rewards off the current maps, instead you obtain a map piece from the chest. After combining several of these, you get a boss chest which has most of the current rewards. It should be possible to balance this such that it's effectively the same as the current maps; it takes 18 hours to get a boss chest map. XI did this fairly well with BCNMs, you could do them whenever you wanted, provided you had farmed the pop items. The only difference here would be gathering and hunting treasure chests is far more fun than farming seals...
