As I was reviewing the marine stats for the updated army book I had a bit of a thought. I don't think single stands of models or single non-super heavy vehicles should use the template for flamer type weapons at this scale. For larger vehicles or titans which use heavy or titanic versions, I have no problem.
My reasoning is this; at 40k scale a normal flamer will typically hit 3-6 models, and maybe kill 3 or 4 using a similar style of attack in epic, you could typically hit 3-6 stands, which would represent killing off 15-30 men, which to me seems massively out of proportion.
So I am proposing that templates for the smaller scale weapons are done away with and the weapon is shot like any other, albeit with a short range (maybe 20cm), with 1 maybe 2 AD and still with the ability to ignore cover. I don’t think a shot from a small flamer type weapon should be able to take out more than a stand, maybe two at the most. The other bonus of this is by not using the template, it will speed up the game. The player doesn't have to worry about laying out the template, working out the best direction to get the most stands and then rolling. He can just choose a target like any other shot, measure and roll his dice.
This change shouldn't affect many units, maybe one or two in each list from the quick scan I did over the army books.
Amusingly though, something like this was partially implemented in the marine list. The Assault Marine Flamer and normal Flamer Marine have 25cm range weapons with 1 AD, 4+ to hit and ignore cover, whereas the Assault Dreadnaught which is also armed with a Flamer, uses the template

And the Furioso and Venerable Dreadnaughts carry Heavy Flamers with 35cm range, 1AD, 4+ to hit, ignore cover, but the Predator Vulkan and Jaghati Khan which are also armed with Heavy Flamers, again use the template.
So I proposing that we ditch the template for anything smaller than a super heavy (I have not problem with a titan roast half a dozen stands as his weapon would be big enough and carry enough fuel for such a thing) and move to using a number of attack dice with a short range (to be decided, somewhere from 20-35cm), as we seem to have implemented partially already.
