Perhaps I overlooked this.
There is a reason that you cannot remove the time limit. It's not about being annoying. It's about RMT. There is a quest that allows you to exchange cruor for a ridiculous 1 cruor to 2.6 gil rate. It's called a chocobo blinker. If you go into Abyssea and farm your cruor chain to max and you get 500-600 cruor per kill and then do so for a couple of hours, you get a good amount of cruor and therefore gil, but nothing gamebreaking. Now remove the time limit. RMT. Gil would FLOOD the market and we'd have another major period of inflation. Think about it. SE cannot allow this. They also have no reason to take this nifty way to make gil while making exp out of the game. It's limited by time. Remove the time limit and the RMTs will just lose their minds farming cruor and blinkering it. You could easily with 2 characters kill the mobs required very quickly while having 16 bots get the same cruor apiece. Then blinker all the cruor. Let's be modest and assume 100k cruor per hour. That's 1800k per alliance. They'd do what? 15-16 hours a day. 1800KX18X2.6. How much gil is that for ONE RMT group (or legit linkshell for that matter). The answer is 84million. ONE DAY! ONE. Not allowable.
Can you do this now? Yes. But once you get tired and go to sleep (you have to come back in) I know you could technically just get like 60k minutes and spend the month in Abyssea. SE has a glitch for that and you'll randomly lose status after a certain period of time. There's a reason. GIL.
