Out curiosity, Why is it that so many people demand that new class/jobs simply MUST be tanks?
I'm referring to posts here about making Ninjas based on Gladiators and giving them shields, or weird concepts thrown out for Red Mages to make them Tanks ... Why do these classes *need* to be Tanks?

I can agree with Samurai being Tanks, Especially as Samurai in general are about Honor (Much like a Paladin), and their fighting style involves evading/parrying attacks made against them. But Ninja? I really can't think of a good way to spin a Ninja in a protective tanky role.
