Reading only some of the posts so I may repeat some ideas.

Adding more restrictions to become a mentor is a good idea, it's too easy to become one.

I think they should add a combination of the following on top of the current ones.

- Play time
- Subscription time
- Fates (like when you get the temptress of fate/tempter of fate title)
- Increased # of level synced dungeons (no cheating using unsynced settings)
- Increased comms amount
- Have at least 1 tank 1 dps 1 healer 1 crafting and 1 gathering job all at lv 60 (increase this level cap to 70 after stormblood is released)
