Don't misslead people about what their job does, please

Wow, I'm a bit shocked by the huge response this got :x

Okay, I'll try to clarify some things:
Yes, there are hints to the roles in skill descriptions and class quests, but like many others said already, those are easy to miss. You have to protect NPCs in dps class quests too, it's not something only tanks and healers have to do.
And honestly, even if you notice it at lvl 15, if it's a role you didn't want to play (which is true for many people who wanted to become a dps but accidently chose a tank class) it means you have to pick another class and level up those whole 15 levels again, this time without any, or at least with less quests. And for a beginner, that takes a while. It's frustrating and needlessly kills the joy of playing at a time when there aren't many cool things yet to keep you playing. Even worse, if you got up to Brayflox without knowing your role, even more levels you'll have to grind on a different class.
(and yes, that's different from leveling up additional classes when you have already reached endgame with your first, because to many people, neither combat is a lot of fun in the beginning with only pressing 1, 1, 2, 1, 1 nor has the story progressed a lot yet).

I just don't understand why there is so much opposition to this
Many newbies are really overwhelmed by the huge amount of things they can do and should know about in this game, they don't even know where to start reading up, even if they are willing to do it, which is not a given either.
I don't see how it is "catering to stupid" to just tell people what to expect of their class when they pick it instead of several levels later.
As Terribad already pointed out:

they should read about what they're getting into. When smart people find something new, they read up on it. SE has information on the website about which jobs are which and what they should to in a party.

It's not like the information isn't existing in any official place. How would it hurt anyone if that information was in the one place every player goes through, instead of hidden away on the homepage somewhere?
All I'm asking for is that SE makes this information available at the class selection screen during the character creation. It doesn't hurt anyone but can help those who get confused by unclear descriptions.

Several people have wondered about the Arcanist.
The answer is actually pretty easy: SE can just write in the class description that Arcanist can either become a even stronger dps or a healer, depending on what the player wants to focus on.
Same with BRD: Call the archer dps, but make it obvious that, as it grows, it gains more and more support abilities too.
If the misleading descriptions for other classes become clearer, Arcanist will be the only class that has information about different job options later. If SE ever decides to add additional jobs to other classes, they can just adapt the class description to that.

In general, FFXIV is a very beginnerfriendly game, especially to those who haven't played MMORPGs before. So why purposely confuse new players with information that is not true, only to expect them to NOT believe what the game just told them in the character creation (like GLA dropping the shield for a sword) and expect them to purposely ignore that official information to wander off to wiki or guide sites that are NOT an official source and read up on their class there? It just doesn't make any sense :/
