Wouldn't increasing the maximum store of gil in the FC chest (suggested: 9,999,999,999) or/and increase player/retainer gil cap possibly alleviate RMT occurrences? IDK why but I'm under the impression that a lot of RMT cases stem from not knowing what to do with all that excess gil that's bound to pile up over years of play, like it or not.
Even with 50-million-gil mounts, they're not helping much as to put a dent in the overflowing piles of gil!
I think this would be one of the best QoL improvements, to me personally.
What do you think?
