Eh, it's fishy in nature, but mechanically speaking it's legit. However I can say without hesitation or ego that to hit 75 in a manner of days while performing little to no activity and having zero increase in skills to do so is by no means (at least by my definition) reasonable or legit. And unfortunately I do see a future flood of unworthy Maat's Cap owners and unskilled relic/salvage/sea/god gear holders.

Not gonna Q_Q over it but I certainly predict this as a logical outcome of said circumstance to AF burn abuse.
