Re: razordons or salamanders in the new book
Here's my 15¢:
Razordons are better if what you really want is a monster. The shooting is mediocre, because you need to rely on the razordon's mediocre BS. In order to have even a chance of putting a dent in your target, you need to be pretty close (ie. within 9'' to avoid the long range penalty), and you need to get lucky with the artillery dice. However, between Quick to Fire and the razordon being a pretty tasty monster in combat, you can play the bastards really far forward. You dare your opponent to charge - if he doesn't, you either charge in yourself, or continue using the mediocre shooting to harass likely targets.
Salamanders, though, are better if what you want is artillery. The template, flaming attacks, and non-BS shooting all combine to make for something that is quite good at putting the hurt on large units, and possibly even causing them to turn tail and run, which is hilarious.
The reason the salamander comes out on top, in the end, is that we already have a ton of decent monsters for combat. Stegadons, carnosaurs, and (figuratively speaking), old-bloods, temple guardians, and big-ass units of buffed up cold one riders. What we don't have is much in the way of super effective shooting, and the salamanders come close. They are just as effective as razordons in close combat, even though they can't put out a punishing torrent of spikes as a charge reaction.
All together, that cuts out a lot of potential advantages that razordons have. The one thing razordons really have that salamanders don't is the ability to target a naked hero with tons of shots and try to nick it to death (templates can only ever deal one wound to lone models). This is a great idea... except who the heck uses naked heroes without protecting them sufficiently? And, since you're relying on 5s and 6s to hit anyway, you may as well kill that sort of target with blowpipe/javelin skink skirmishers.
So, it's salamanders all the way for me. Razordons aren't bad - it's just that we have other stuff to do what they do, and nothing else that does what salamanders do.
