They have slightly lower VIT and STR (and CHR like you said) compared to the Hume in which they edge out on against the Mithra. So if you are going for a PLD or WAR/MNK-ish tank, Hume will edge out instead of a Mithra. Other than that no problem.

Rumor has it that CHR affects Provoke hate...this is not proven.

I have the problem of Mithra and Hume xD You cant be extrodinary like Taru PLD or Galka WHM. But you can do most things decently, which means they suck at all, but dont extremely suck at all :P
