Even with the new additions, I still consider the strongest race present within the group to be the Hobgoblin group for stability concerns. Not to say that some of our newest additions lose out in firepower. The Lords and Drago-newts certainly are of a similar degree of power.
It's not a problem since they all joined in separately with no attachments to one another. But the fact remains that alone, I would be hard pressed to quash a mutiny should it arise. More or less, the reason I am in charge is because I am the strongest member of the group. For now, that remains the case, but in the future, I will need to make sure that I remain as such or risk losing control of the group all together.
