1 - I don't remember to hand in for 2 weeks and you want to increase my pain?
3 - Would make it too easy to get 3 lines.
4 - You can only reroll at 7/9 or earlier. This was done intentionally so I don't see why it would change.

You have only been doing it for weeks but I have been doing it for years and have not got 3 lines. It's intentional but you can actually buy the rewards on the market board if you are impatient.

The only improvement I want from it is for it to require Minimum IL and Silence Echo settings and to include savage. It's ridiculous that we have a Blue Mage log successfully motivating people to do extreme and savage synced but Wondrous Tails isn't doing the same for normal jobs.
