I'll take blame for the change in the articles mentioned- I've always been a little long-winded when it comes to typing, so what were intended often to be brief looks at odd designs often became far more extensive than the TRO entries themselves! That was often the case in the Vehicle articles, and when I'd fill in on MotW it came through here as well. I admit I miss working on those articles sometimes, almost as much as I miss CWD being around.
Anyway. Ryoken II. Yeah... at a glance, this looks awful. Twin LRM-15s are never a bad way to start the show, and 5/8 is pretty much par for the course on a Clan heavy (though looking at the artwork and miniatures, can you imagine something shaped like that moving that fast?). And then... LB-2Xs. One is a strange thing to pick for a weapon- four seems almost criminal. And then... Then you start really considering the machine's role. Is this a Mech fighter? No. No, this isn't going to win against another Mech often. But against just about anything else? Meet the Rasalhague Murder Machine. If it flies, it's going to cease doing so very quickly after meeting a Ryoken II. Ground vehicles had better set their parking brakes, because they're going to be immobilized in no time flat. And few units will even be able to reply while under fire from those chattering cannons. As a support unit, this thing shines. And what do you know, it seems vehicle and infantry forces are much more prevalent than Mech forces in the early portion of the Dark Ages... how convenient for Ryoken II drivers!
Now, I don't have experience firsthand with the 2 or 3 models, so I'll reserve judgement, but it appears that adding heftier guns was only a mixed success, tempered by a pretty major loss of armor plating. Not a fan of those changes, though at least the 3 remains a killer of all flying units.
Now, Tassa... I'll politely disagree with the author here, in his belief that she should have had a more iconic unit. Part of this, of course, is that the early Dark Age sets didn't feature the Mad Cat- they had the Mad Cat III early on, and the Mad Cat II (which oddly used the old Mad Cat look) eventually, but early on this is what we had for a Clan heavy- this and the Tundra Wolf. Well, we already had a character in the first novel using one of those beasts, so.... something different for the second novel made sense to me. And at that point, we didn't know this was a Ghost Bear machine- just that it was Clan tech. And what a Mech she built out of it. Hard to argue with twin ER PPCs backed by Streak racks. The lasers do feel like an afterthought though- replacing them with another ton of ammo, as suggested above, is a good move. With the Dark Age being heavy on infantry forces, I'd look at swapping the other for a couple of flamers as well, but I've always been a bit infantry-paranoid (as my canonized designs tend to show). Otherwise, hard to argue with this thing's layout- it feels like a Thor configuration in a lot of ways, and with my love of that machine it should come as now surprise that I'm a big Ryoken II (Tassa) fan.
It's hard to improve on these... leaving the 2 and 3 alone, the 1 might get a boost from switching out two of the cannons for ER large lasers, allowing heavier punch and similar range without a huge increase in heat (especially since it clears weight for heat sinks), but it means less cluster-flak per turn. It's at least worth considering. As for Tassa... other than my suggestion for more ammo and flamers in place of the lasers, it's hard to come up with much that improves that monster.
All in all, a machine that is dog-ugly, but if you use it for the jobs it's built for this can be a true terror on the modern battlefield to non-Mech forces.
