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

I started my first character as a gladiator, expecting to be a damage dealer. I'm someone who does pay attention to what the game's telling me, so by the time I entered my first dungeon I knew I was supposed to tank, but even so, that would have been pretty late to find out if I hadn't planned on doing everything at some point anyway.

For somebody who didn't want to tank, getting 15 levels in and only then finding out that the class they'd been leveling that whole time isn't even the role they wanted would be quite a blow. (Those of us at 50 or 60 now may not think of the first 15 levels as amounting to much, but to a new player who's only gotten that far they are. Many people feel very invested into their characters within just the first few levels, and when it's the entirety of what you've played so far, it's a lot.)

It's all the more important to be clear about roles in a game that's moving to a different genre than the majority of its franchise. I think XIII is the only one of the single-player FFs to even have a tank role, and some don't have a dedicated healer either. The notion of group roles as they exist here is more of an MMO thing.
