Making a balanced narrative list

[ilovethenids]

I just wanted to see what people think of my list I'm working on for a narrative custom mission, I want to make sure it feels both fluffy and balanced. I will be creating another thread in the Other Army Lists forum for the opposing list, as I want to make sure the two are balanced against each other. The scenario has three objective markers within the 'nids deployment zone, each worth 2VP at the end of the game, but the opponent automatically gets first turn. I'm going for 2000 points.

Battalion Detachment: Kraken
2 Tyranid Primes with boneswords, deathspitters, and AG (1 of which is the Warlord)
3 units of 30 Hormagaunts
3 units of 3 Warriors with boneswords and Deathspitters
Vanguard Detachment: either Kronos or Kraken (the fluffiness of having detachments with different Hive fleet choices represents this particular Hive Fleet's exceptional adaptability, but I may decide to stick to a single one just because Synapse doesn't work with 2 different Hive Fleets)
Tervigon with AG, ST
30x Gants with 10 devs
30x Gants with 10 devs
3x Warrior, 2 with deathspitters, 1 with venom cannon
3 units of 3 Hive Guard with impaler cannons
1 unit of 3 Pyrovores

Now I know HG are one of our better units, the reason I feel that having many of them is appropriate is because the objectives in the game represent nest-structures that the enemy is trying to destroy, and in the fluff, Hive Guard are often used to defend Tyranid structures.

EDIT: Here is the SM list that it would be going against: thetyranidhive.proboards.com/thread/56575/balancing-narrative-sm-list

IT's always hard to comment on 'fluffy' lists, because good fluff is a matter of personal taste. However if you want to tweak for a bit more effectiveness. Try putting 2 units of hive guard together for one squad of 6, that way you can use single minded annihilation on them to greatest effect for the CP cost.

The reason I was planning on 3 units of 3 was mainly to have one unit at each objective. Someone brought up a good point about the SM vehicles being a potential problem for this list. I could certainly scrounge up the points for more venom cannons (the list is 30 points short of 2k as-is) on the warriors, and I imagine if I got rid of one of the big gant/gaunt blobs (and the Pyrovores) I could squeeze more Hive Guard into each of the three units to add more anti-armor.

Luckily, it is an objective-based scenario, so part of the idea was that even if the 'nids have to ignore some of the vehicles, the list has so many bodies that it will be hard to get through enough of them to secure them. Still, I will see what I can do to add more bite.

Well, I've made some changes to the list to give it more punch against vehicles. Here's what I've got:

Battalion:
HQ: 2x primes with AG, BS, DS (Warlord)
Troops:
2 units of 30 Hormagaunts, 1 unit of 20
3 units of 3 warriors - each has 2 with BS and DS, 1 with ST and VC

Vanguard:
Tervigon with AG, ST
2 units of 30 gants with 10 devs
3x warrior - 2 with ST/DS, 1 with ST/VC
3 units of 4 Hive Guard with impaler cannons

Now I am not sure what I want to do for the Hive Fleets, I was originally thinking a mix of Kraken and Kronos, but I can't decide because while I really want to give the Chameleonic mutation to the Tervigon, the detachment it's in would benefit far more from the rerolling 1s to hit with shooting. I also couldn't come up with a way to fluffily make the list where Tervigon was part of a decent Kraken detachment with everything else Kronos while still being relatively viable (mainly because of Synapse). I'll probably just run full Kronos, as I might try out an idea I had for a sort of "Look Out Sir" where the Tervigon could pass on wounds (not damage, just wounds), as Mortal Wounds to a unit of friendly <HIVE FLEET> termagants within 6" on a roll or 4+ (would encourage the enemy to whittle down the gants a bit first, would help negate the giant target on its back being the only MC in the list, and would be suitably fluffy). That's not the topic of discussion though, so I'm really just trying to make sure this list could fair okay in the scenario described against the Space Marines. Partially because I plan on having most of this stuff commissioned, and I want to make sure I have a good list before I tell them what I want to have done.
