I understand this is a 'long term goal', but 3000 A ranks and 2000 S ranks? A bit too much? I consider myself an active hunter with multiple hunt linkshells and try to never skip S rank, but still have only 1200 S ranks killed since the moment they were introduced in patch 2.3. Those with less time to play probably have less then 300.
At this rate, most of people will never get this mount.
