15% Crit Ring, worth it?

For level 120*, which should be assumed anyway since a vast majority of people are reasonable, have lives, and won't get a mule character to 210.

Does Beast Tamer even have any skills past 120? I looked through the extraction and the highest ones are 120, which leads me to believe you'd only level up more to unlock the other 3 spirit animals you hadn't had enough SP for yet.


Or if you want to use that sick party-buff (% exp, % crit, atk, ...) in somewhere with a level limit.
