Superficially, the two families seem interchangable, I know, but it's worth considering that they're actually quite different, with the Velocidrome's group relying mostly on jumping, whereas the Great Jaggi and its relatives use tail swipes and hipchecks. Both like to bite, but doesn't every monster?

I guess the largest degree of overlap is between the Iodrome and the Great Wroggi, but even they have distinctive traits, like the poison fluid versus the poison gas.

I guess those differences don't really mean that the shared identity of 'pack leader' monsters is insignificant, but as things are, both are present, so the more the merrier.
