To edit and give further explanation on my previous reply, Queen Penthesilea is nice to have for most all fights unless facing a defensive tank. For instance, if she is pitted against a Saffron or Ahmose Nekhbet when their shields are up she is doooooomed (at least doomed for me since i dont have her tanky enough nor do i have good morale manipulation). So there you would find that Ahmose Nekhbet would be the most effective tank, most definitely. I agree with Jupitor there. But in many instances Queen Penthesilea is like a faux-tank and a damage dealer in the long run.
