The game will more than likely one day have a 4th tank. I was curious what people thoughts were concerning what this may be.

As far as I can tell, the main thing that it would have to follow, is the abiliity to wear plated armor, since SE likes keeping tanks in the same gear. The big issue is that as far as I can tell, there really are no more plate classes among final fantasies various jobs, so it would likely have to be something unique to FFXIV. Likewise, the mechanic would likely have to be somewhat unique too, since there is only so much you can do with tanks mechanic wise.

In my mind, I see 3 potential future tanks.
1. A gun blade wielding Garlean like tank. Since 1. It's a crowd favorite. and 2. Plate
2. A beast master that duel wields axes and has a sort of pet focus, if only because I can see it wearing plate, and I feel that such a class would be unique.
3. A heavy armor toting magitech cannon user. For above reasons: having a minor range focus would make it unique.

I don't want to go into much detail on what each would entail, since I don't want to have the thread focus entirely on my thoughts, so what do you think a new tank would look like?
