Just a reminder:
2) If they are perfectly merited for one job, it presents the biggest balance threat when given more merits because you have to assume that they would be on that job in situations that require high performance, the hardest events.
3) If they are perfectly merited for one job, any future merits that they obtain from having the cap increased will necessarily be less valuable to their job than the ones they already have.
4) Optimally-merited jobs barely benefit from increasing the caps.
Simply raising the cap accomplishes nothing, and adding more merits does just as much.
