Yes, Kat 3 is partially because the original crashed out so early, but Fire Storm, Behemoth and Hydra are rejected because they're still in, or are pretty much guaranteed into the quarter finals. Despite the earlier versions of those robots having different weaknesses. If it's a question of the Kat 3 robots being too similar, I disagree. Even the series 6 Kat 3 had different weaknesses to the series 7 one, a greater inability to self right, a weak axe handle that snapped when trying to right itself, more of a vulnerability to flippers as there was no wide base to accompany the tall robot. The series 5 version couldn't self right at all, was slower, has a lower centre of gravity, I believe a weaker axe, perhaps evened out by the greater swing, as well as a completely different shape and more exposed wheels.
