Mentors...please!

[RajNish]

You are right that is why the achievement is called "leaving a good impression". However since commendations are part of the mentorship requirement they are suppose to be more than just a glamour thing...

A mentor is a player with the knowledge and the will to share it with others so the get your job at max level is part of mastering your character (but summoner/scholar/jump potion made it irrelevant for a lot)
The 1000 dungeons is for mastering dungeons/raid/trials/guildhest mechanics (but most will just do ifrit for ever)

So the first two criteria are about the knowledge and now we are left with the will to help/guide others with said knowledge and that is perfect because we have one last requirement: Commendations!!!

In fact, getting a crown is quite simple now. I have heard stories about people who just "farm" recommendations. Will these people help others? Very little chance. I do not think that such a stir would be for watering can icon.

I do not think that such a stir would be for watering can icon.

But other status awards remain: title, achievements, mount.

Just saw a charming "mentor" who didn 't give any advice, although the group is more than once are wipe, and at the end no roll items to wait until the other players had the patience and left the dungeon.
You can see an experienced person right away.
