So to preface this, I think Uthuk are overpowered, but that isn't what I want to discuss.
Rather, how do people think Fantasy Flight would deal with an entire faction that is imbalanced? Would they try and bring up the other factions via fix upgrades that are more powerful for their points? That would take a while, and may lead to power creep invalidating old options. They could nerf powerful upgrades, although if part of what is powerful is the units themselves, changing dials or unit cards seems harder.
Anyways, I'm curious how Fantasy Flight has handled this sort of the thing in the past and what people think they would do if a faction was acknowledged to be significantly better then the other options.
