Like someone else mentioned, end game mobs aren't really that liner, though some are "harder" than others they're all such different type of fights that they're not really linear. My ls had killed only Genbu out of the sky gods by the time we had our first ground HNM kill (fafnir)when we found it up unclaimed once, and we'd likely have had more but that was back in the day when JP ls's still claimed 99.9% of everything on asura, so we tended to focus on sky more for a while. If you have the people and jobs to take on the sky gods, you can take on any of the ground kings with knowledge of the right strategies and a bit of practice.
