All this discussion on whether the requirements for mentor are too high or not. Fact is, if this is anything like FFXI, you avoided anyone displaying a "mentor" flag as they were invariably all ego and no ability.

FFXIV doesn't need a mentor system. Really, how many new subscribers are they getting that would need this feature? It's being added not as a benefit to new players but as more "content" for existing players. That is why the requirements are set as high as they are - keep those subscriptions sticky!
