Tiger mount requirements are a little bit too high?

This is assuming your on when they spawn said S ranks. I hunt a lot but unfortunately someone likes to spawn all the S ranks a few hours before I get on each day. A ranks are easy but the S ranks im still about 100 away from the 500 achievement and I hunt a lot and try to go to every single S rank. Lower that requirement down to 1000 S ranks.

Also 2000 mentor you can do at your own pace and anytime to build up progress, hunts you can not.

My point is being your have ample opportunities to build up to that large number. Neither are meant to be easily obtained in the sense that they want you to invest a sizable amount of time for them.
