Good article, to be sure. I've always favored giving historical background, so I liked that section. I might have put a bit more weight on the post 3050 IS, to give a good idea of how the Jinggau stacks up; the 5/8/5 heavy lineup is pretty thin, with the Falconer being the gold standard, and the Quickdraw as more of a lesson in why you need an XL (though with some weapon tweaks the poor Quickdraw can be at least usable) .
As for the mech, I've long been on the fence. The Falconer, and the Summoner that was its inspiration, work for me because they have both speed and range. The Jinggau looks like it does too, mounting a GR, but the sinks and lasers tell the story of an infighter. Its a good one, powerful, but it requires you to take some risks. Given the C has historically liked range (Vindicator, Catapult, Cataphract) at least one sniper in the family would be nice. Maybe a LRM/ PPC option.
But its still a really good mech. The 8 has more options, the 7 knows what it wants to do and sets out to do it. The Ion Rush I'd guess is the Maini Domini hunter. They take a lot of killing, and the sort of things the Grandmaster of the Warrior Houses would protect tend to be prime Blakest targets.
