I'm looking at the pricing and the use of handgunners. The question being asked is are they over priced and the answer I have come to is
A) No if you accept Fandir's theory for high elves
B) No if you don't because they are really strong in their own right.
What applied to handguns applies to crossbows. The difference being that crossbows don't have AP but have longer range.
They are units I think were you need to take loads of them. (say 20+ in a unit) but they are very powerful and 20 handgunners is on 200 points
And while I love the idea that handgunners are "strong in their own right", could you go so far as to qualify what you mean without completely inappropriate comparisons to other Empire units that do a fundamentally different job in the army list.
Even so, if we are going to consider your Demi gryph comparison above, why is the demigryph player playing like a complete spanner? Why did he not stop 24.5" away from the handgunners on the first turn (out of range), then march 12" on the second (still at long range) then attempt a fairly safe 13" charge (long range and stand and shoot), taking one round of shooting at -1 to hit and the stand and shoot at -2 to hit?
Now even if we assume a wide formation of 13 across so they can all shoot 25 shots only gives you 8 hits at long range, which is 5 wounds on T3 and approx 1.8 wounds after a 3+ armour. The Hurricanum does NOT give you +1 to hit from ranged weapons.
The stand and shoot reaction will be even worse as long range and S&S mean your Hgs will only Hit on 6s, so from 25 shots, approx 4 hits, 2.8 wounds, say one wound unsaved. With slightly above average rolls you might kill a single Demi gryph before they were wrecking your face in combat. Now if you assume the demigryphs also had a hurricanum things are looking very grim for the handgunners.
I'm also a little concerned about how your handgunners are getting 5 points of combat resolution. In order to fire all their shots they must be in a formation with two ranks and a frontage of 13, let's assume that they do convert a wound on a demigryph, with their rank and standard that gives them a CR total of 3. They also won't be steadfast in the second turn of combat because the gryphs will have eaten their back rank by then.
I also couldn't help notice that while you highlight the fact that the Demi-gryphs have a 40% chance of failing their Ld8 panic check, you also assume that the handgunners will automatically pass their Ld7 steadfast break test, biased much?
Why do you think 8pt handgunners would be too cheap? They used to be 8pts and Ive never met anyone who thought they were too powerful, I used to bring a unit of 20 crossbows (also formerly 8pts) and they never did anything for me other than drop a few models off the back of a unit here and there. It wasn't like handgunners were the "OMG that's so broken" unit of last edition, it's not like everyone took them in multiple or massive units and wiped out entire armies from a distance. Now they're just as bad as they used t be, but they cost more.
Even regarding Fandirs theory handgunners are still terrible compared to either the HBVG or outriders which do the same job in our list, and granted they are core rather than special or rare, but I've long believed that while core units should be less powerful than those in the special/rare section, they shouldn't be worse value for points.
