Seravi may be a little blunt, but the points are valid. And no, you can't judge a player's ability based purely on their gear, but when you factor in their apparent gear and achievements as a context for their strange assertions about how a class works, you can at least start to draw some...correlations. E.g. There are skilled players without any Dreadwyrm drops, whether due to RNG or lack of time or group, but most of them are regularly doing content that naturally helps to upgrade their gear. They typically aren't running around with Weathered pieces.
And yes, healers are to assist DPS when it is appropriate to do so or they are bad, just like the player of any other Job who insists on doing the bare minimum and stands around being unhelpful once they deem that requirement to be satisfied.
