Raise the minimum allowable job level in Abyssea from 30 to 70+

[Zeitzone]

As a linkshell we have an unstated rule regarding Empyrean weapons from Tahrongi Canyon. If you want one there, you're going to AoE burn for chests and most of the linkshell is going to leech a job.

As a team, there are several of us opening the contents of chests for keyitems while other members of the team focus on killing shit. By working as a team, we maximize the number of chests we obtain. If we were to do this on a level 90 job, it's unfair that we get no reward (from exp chests) for helping our linkshell members obtain their empyrean weapons while we take on the incredibly important task of holding key items for them.

Level 90 still gets Merits for exp. So chests arent for waste.
