There's a very wide field between mentors unsyncing Ifrit because the new player can't get past it with trusts and "why haven't you watched a guide and gone to the Balance so you can practice The One True Rotation on dummies for hours" for normal level content. And we never going to get an agreement where we should settle between that and how we do get people there. I don't think either extreme is something we should aspire for.
And every patches you run the chance that the job you knew got a rework and you start at learning again when you just wanted to see the latest ear wiggles the NPCs can do but you can't.
