It probably should be hours played a certain job that grants you the ability to mentor for that particular job, or maybe number of instances when playing a specific job. A lot of hours, but I haven't decided how many.

The current requirements suck because it's easy to get 300 comms and three jobs to 60. You don't even have to know how to use a job to get it to 60. Level should not be a requirement in and of itself. The 1000 instances is an ok-ish requirement on the face of it, but honestly, across the 15 or so jobs you could have gotten your way to that and still not be an expert at a particular job.

As a career healer I *could* level a tank and dps to 60 running fates and really not doing much with them, but why should I have to do that to mentor as a healer? They clearly have not given mentoring enough thought. Too many of their decisions are rather easy to pick apart as being flawed so it makes me wonder just what goes on in meetings sometimes.
