I enter the battlefield too...
regardin' the Varanguard issue:
Varanguard get to reroll failed hit/wound rolls if you take the Everchosen battalion (I did).
(snip)
Guard are incredibly powerful, I had a group of 10 with a rerollable 2 save hold up archaon for 3 turns before he landed a single slayer of kings roll which took out 3 of them. You are underestimating Varanguard.
Varanguard are strong, but against 15 buffed guards?
Correct me if I'm wrong (never faced them) but on paper 3 varanguards deliver 9 attacks with fellspears, 3+/3+ (+2/+3 with archaon, but at that point we have Starlight). 18 attacks with Relentless Killers.
On average, on 18 attacks you'll have 12 hits, and then 8 successful "to wound" with rend -2. 4 will be saved, so 8 dead guards.
I don't know what formation gives to them, but if Varanguard have the Everchosen Battallion, then Guards should have their eternal starhost, starting at save 2+ without magic. Have fun when your weapons deal d3 dam.
let's say that they wipe away 8 guards, the other 7 saurus guards will deliver 22 attacks at 3+ 3+, dealing d3 dam.
That said, if Varanguard deal so much damage, and on average (tnx to buffs that i don't know) they can kill with ease more than 8 guards in their charge, then simply form a veil with disposable skinks between them and your guards.
Or deal with Varanguard with shooting. Let them charge your guards, and blast them with sallies. Bye bye everchosen.
My suggestion, anyway, is to use a starpriest, not only for the Starlight, but also for the Serpent's staff, that will buff the carnosaur...
thus introducing the carnosaur issue!
Anyway I was just wondering what the personal experience is of Scar Vet vs Oldblood, as I echoed earlier I always seem to struggle with my Oldblood. I ran a Scar Vet today, didn't do too well. Other than positioning monsters, any ideas on how to make shooty units not slap them silly with wounds or is it just something I have to give up and deal with?
If you deal with high rend guys, probably a Bastiladon would serve you better, especially if you consider that agains chaos demons the beams deal 3 dam. Varanguards will take just 2 dam, but won't be able to kill the basti.
Anyway, we're talking about carnosaur.
Both of them are good, 'cause their bloodroar will help you (you kill one Varanguard? battleshock test! the other two won't flee for the battleshock, but you have a chance with the roar)
IMO, the Oldblood should serve you better, for the following reasons:
The oldblood will give shooting support; it may be weak, but rend -1 is nice, and gains +2 Vs chaos demons
Carnosaurs are fast, you don't keep them in the frontline, but you do the countercharge: doing that, you will attack first, so better do deal heavy damage rather than a slightly better defense.
Shooting against carnosaur could be a problem, but you'll notice the difference only if the shooting got rend -1
