When it comes to Clan Mongoose, Era Report Golden Age pretty much quintupled what we know about the Clan, so its as good a time as any to jump on board (I don't know how long that was out for, but no one told me, and I only recently stumbled onto it. What the heck, guys?). The Great Wyrm thing is generaly my little joke, since as far as I know its the only Mongoose mech, and its actualy pretty sub par, if eminantly usable.
As to the lists in general, what we're not looking for are mechs that are good. What we're not looking for are mechs that you enjoy.
What we do want to see are mechs that, when you look at the omni kings, the mechs you've chousen are better.
The Incubus is one of my picks, so let's put it to that test. The nearest very fast lights are either smaller like the Fire Moth, or slower like the Hellion. The Phantom has the same speed, but it gains tonnage, and it still dosent manage to be better, unless you've got a tactical situation where you can make the brutal C work. Even if you go to the Ice Ferret, which is still slower and much larger, you've got big gun veriants with either a PPC or ER LL, and the PPC one's got no secondaries. I'd take the PPC Incubus over it, and the LPL model over either. Against the Hellion, again the Incubus has the advantage in speed, and the best Hellion models tend to be geared twards more power in the middle ranges vs accurate power at range, so its a bit of a wash, but the combination of speed, accuracy and range is very compelling. You can't easily point to a front line omni that is better, or even on par, with this second line mech. Granted, the LPL is a big seller here, and a custom Ice Ferret or Hellion or whatever could mount its own LPL can top it, but they don't. And even then, they'd still be slower.
Can this be said of some of the other mechs? Is the Guillotine IIC, which is a very popular pick, better than the Night Gyr? Or the Nova Cat? Or the Timber Wolf? Or is it just a good mech that's fun to use, but still overshadowed by its more powerful brothers? People said that about the Shadow Hawk, you know.
