Relatively large concern about new Healer: Sage

[Lumivyory]

Okay everyone is saying that the people who play Sage will be bad at the Job of Healing since they start at Level 70.

Nobody is saying that everyone who will be playing Sage will be bad.
The concern is about those people that never played a healer before and simply don't know how to. Healing can be overwhelming when you're not used to it.
And we've already seen a million clear examples of people not knowing what they're doing after boosting a job to 70.

Now that I think about it, it's scary that soon we'll have job boosts to level 80..
