So I had an offer of a trade recently which included several Forgefiends and a Maulerfiend at fire sale prices. I didn't jump right on it because I recalled that I looked at them when our CSM book first came out, proxied them, and found them severely wanting. Even so, I figured this is 7th Edition right? Aren't vehicles supposed to be tougher now? That is what people keep telling me (although I certainly don't have any trouble killing them). Given the crazy value of the trade I figured I'd take a look again and see if now, years later, if I found I had misjudged them. I don't run into them very often (well almost NEVER) so I can't be the only person who found them wanting. Even so, I went and gave them another close examination.
Forgefiend:
Ostensibly our "volume of fire" walker, the Forgefiend compares badly against the like units of other armies and even worse against the similar options within the CSM book itself. Consider if you will, that a Carnifex decked out for shooting costs 5pts less than a Forge Fiend, fires (4) more shots, is twin-linked, can't be blown up, shaken, stunned, etc. and has the added perk of being absolutely deadly in close combat. Let's not forget the wonderful high strength Hammer of Wrath. There is also the added perk that you can stack those Carnifex up in units. I won't go on and on grabbing the volume of fire units from every codex but the pattern repeats. The Forge Fiend is overpriced and underperforms. The nail in the coffin is, of course, the fact that for barely a pittance more you can get three Obliterators that can do everything the Forge Fiend can and are much more durable. It is like they were drunk when they created the stats for this thing. One also has to wonder about it only having (3) Hull Points. It is huge and looks well designed. Apparently not.
Maulerfiend:
It has this much going for it; it is better than the Forgefiend. That being said, that isn't a lot. It is fast. If it hits it gets 1-2 extra nasty attacks which are really good for killing vehicles and buildings. That is about it. The problem is that for a dedicated combat walker, it isn't particularly good at its job. It is only WS-3, so for all the cool description in the book, the thing is actually no better at close combat than a damn Guardsman. It only comes with (2) basic attacks, so even given one for for the charge you will have to assume it is going to need 4s (or 5s) to hit. Since its Magma Cutters key on hits, that is something of a drawback. It does have the fact that it is relatively cheap compared to its worthless Forgefiend brother. Not too much more than a Helbrute, I suppose it is possible to spam them if you don't care about the fact that they compete with much better Heavy slots. Still, in 7th Edition, it really isn't difficult to get all the slots you want. If I had to run a Fiend, it would be a Maulerfiend. The main issue, of course, is that their primary purpose (the only thing they really do well) is kill vehicles and buildings. I suppose one could run (3) of them if you could find a way to get the slots or just went Unbound and three of them is around the cost of a single Knight. Eh. Even that doesn't really pan out. It really would take all three hitting intact to take a Knight down. Given the fact that they are glass cannons, good luck with that.
I wanted to like this guy, but he is only slightly more useful in theory, and in application will likely just get trounced.
