Will there be an increase to levequests allotment coming up and possible new content?

Currently we get 3 levequests every 12 hours; so 6 per day. Looking at some of the achievements that are set in place today you need 10,000 battle leve (Region d'Etre) in order to get the highest achievement. At 6 leve max per day you are looking at 1667 days or over 4.5 years to complete this achievement.

I understand putting a goal for people to achieve in the future, but there are similar achievements for field and craft leve. To finish these 3 achievements will take over 13 years. Also I see zero reason to do any more leve on my jobs that are 50 as the rewards outside of xp are not really worth my time. Will there be any emphasis on making the leve more rewarding for players that are at the max level?
