Hit Level 30 in just over one week without even finishing all of the Release 1 objectives, thanks to receiving high amounts of unearned XP during the period when all of the Field Passes were screwed up.
Even without that, it's clear to me that the whole pass, designed to last the same length as Season 2, was flawed from the start.
Even if it had been possible to progress through the MF FP 'naturally', it's highly likely that most people would have reached Level 30 during Release 3 at the latest anyway.
Seems to me that the only way to save it is to add more levels.
