Please Do NOT Introduce Another Melee Tank

[Reynhart]

The only real way to have a "ranged" tank is to have a job where the pet is the tank and the player himself was not very strong at all. I kind of doubt this will happen, but it would be interesting.

That's a pet tank, and it indeed could be interesting.
I haven't played SMN on endgame, but I doubt that Titan can hold aggro over strong DPS and on multiple targets.
