One of the notoriously well known items Maat's cap has a basic requirement of having 15 jobs level 99, therefore this is proof that the current state of FFXI promotes us to level more than 1 job.
You mean 66.

Maat's cap was always intended to be a trophy. I don't disagree about leveling multiple jobs, because that's obvious, but Maat's cap has nada to do with that.
