It was never my intention to compare the VAoD to anything!
I am saying that Vulkans aren't all that bad, and are not in need of fixing. Perhaps, some gentlemen's rules need to be observed - call it a "Cheese Rule." If a player wishes to field Vulkans, he should, then, not be allowed to take another squad of Vulkans without, first, having another Elite Unit (or, possibly, two Grunt Units) in his/her army. Perhaps, make them a support option that may take Elite loadouts.
Then maybe you should compare the VAoD to some other roster? All legal forces cost some PCs, so they should be comparable. If not on a single unit level, then at least on army roster level.
Maybe some insights on polish tournament rules creation process will cast some light on matters. The first UWZ tournament was played according to rulebook (no rule was changed, we used the latest FAQ and obeyed all answers from the old message boards we could find). The outcome was a disaster. People brought (for 1200 PC armies) 4 full squads of Praetorian Stalkers, 4 squads of Shadow (Nagano) Walkers, 4 squads of Ronin Light Battlewalkers, etc. We had to enforce two rules (to make the rosters more diversified):
-You can have up to 2 elite squads of the same kind
-You can have up to 2 support squads of the same kind
Thinking that this would end creation of more tournament rules, we held the second tournament. Only two "cheesy" roster survived those changes. One of them was Bauhaus, with 2 squads of Vulkans (and optionally 2 additional squads of Viktors as support), while the other one was Algeroth roster, with maximal number of spell caster allowed (I think the number was 5, when you're not counting Centurions), making mayhem with the Apocalypse dark symmetry gift. The second problem was rather easy to solve - we changed the gift's template size to small.
As for Vulkans, we made a poll on polish warzone forums, for people (playing Bauhaus and non-Bauhaus factions) to chose the needed limitations. 53 players voted, and the result were (detailed limitations / votes / % of votes):
-change the MHMG to MG-80 HMG / 25 votes / 47%
-add 15 PCs to each Vulkan model / 12 votes / 22%
-limit them to 6 models per roster / 5 votes / 9%
-add 10 PCs to each Vulkan model / 4 votes / 7%
-change weapon to some other weapon (not MG-80) / 4 votes / 7%
-limit them to 3 models per roster / 2 votes / 3%
-remove LR weapons range / 1 vote / 1%
As players decided, we enforced the limitation supported by the highest number of players. (and yes, I know that % of votes doesn't add up to 100% - blame phpBB authors for poor math, as I am just copying those numbers from polish forum)
well, basically everything is said... it depends on the terrain-density
if the vulcas can use their LR Mhmg well, then thy will be very much worth their points!
if they need to engage in MR, they will suffer/be in attack range of "mundane" weapons (eg not the MOUTNTEDhmg ).. esp. if the meatshild is not so thick.. in dense terain, an 8 model unit will take some space.. and if they are totally dense.. there are placed templates..
however: a 5+sgt+2hmg assault marienes (240P) will be simmilar to 5 vulcans with some eqip
15 A vs. 24 A, but less armour, wounds and weapons => vulcans are not totally out of ballance but they are an exelent buy!!
As I know at least some inner workings of the point cost formula, I tend to agree. Vulkans price is correct. And this is scary, because the flaw lies in the formula itself. To this very day I ask myself why no other army has elite squads equipped with MHMGs?
Vulkans are cheap because they don't suffer from "overloaded with special abilities" syndrome. This can be observed well in Pathfinders statistics (p.270). A elite model with 1 WD and 18 AR cost 57 PCs. The same as Viktors (2 WDs at 23 AR). At first glance you may not see where the error is, but a closer inspection (with some cost figured out) reveals that those special abilities cost a lot of PCs. And Pathfinders don't need the third weapon, as two of them (Aggressor Sidearm and Iron Bolas) work almost at the same ranges. In the end you get a Grenade Launcher with wonderful special abilities, paper armor, that costs 57 PCs. So we got a good shooting unit up to MR range, with high AR, two WD and a Grenade Launcher, with excellent abilities, hindered with low AR, and only one WD. I personally don't know any player who would choose Pathfinders over Viktors, on any kind of table (including a dense one, like Dmcgee1 showed). Something isn’t right here, and it appears to be cost of those special abilities. This is not the only model suffering from the "overloaded with special abilities" syndrome, but it’s one of the worst cases of this disease.
And there is one more thing that makes Vulkans so attractive in the realm of unit costs - MHMG cost few points more than HMG, and is a lot cheaper (two digit cost difference) then Mounted Autocannons. This anomaly is not supported by the change in weapon effectiveness. It's the other way around. MHMGs are better than Mounted Autocannons, and are far superior than HMGs (compare them yourself, if you don't believe me). If you combine those two unrelated flaws in the point cost formula, you are mixing ingredients for a super cheesy unit.
Maybe this was done deliberately, maybe this was an accident in unit creation - I really don't know. I'm not willing to judge anybody. I just analyze unit costs, and from time to time I need to stop, go outside, and try not to think why some flaws in this formula were introduced in first place...
