Right, I think we should probably go up to 10, yes...but I think the 3 S4 attacks is appropriate for the following reasons
Dryads, a similar core unit, have a ward save and T4, w/ 2 S4 attacks. Thus, they have 1/3rd less offense, but vastly improved defense, so I think the two are comparable.
Ghouls, which as you correctly noted these are meant to replace, have essentially the same stats, but with S and T switched, plus poisoned attacks. It seems to me that the lack of poisoned attacks and the much more sure casualties that go with them necessitates a suitable replacement, and so it seemed logical that more (but less sure) wounds would be a suitable switch out for fewer (more sure) wounds.
Plus, the 3rd attack isn't guaranteed, and they'll only get it as long as they keep winning (I believe frenzy still works that way.)
That said, I think anywhere up to 12 points would be perfectly reasonable. Or giving them A1 + Frenzy, though that would almost certainly bring them back down to 8 I should think.
And in regards to the
stupidity issue, I think having them just stop once they hit that range makes the most sense...if nothing else because it makes things just a little bit simpler.
Oh, and for what it's worth, thank y'all for making me feel very welcome

I look forward to working on the other 4 variant army lists
