Daily quests for earning red and blue scrip
The Ixal quests were perfect for casual players. They didn't take long, workshop buffs made each craft unique and interesting, and the supplied materials removed any gil requirements. Why don't we have something like this for scrip?
Daily quests that let you earn 75-100 of each scrip per day could help all players earn their master 3 books and cap red scrip each week. Hardcore players could still farm collectibles to earn scrip faster. In that way, it would be very similar to farming dungeons for law and esoterics with roulette bonuses for players short on time.
It wouldn't fix everything, but I think it would be a step in the right direction for a system that a lot of players are obviously unhappy about.
