Turn 2
2 Lictors teleport with no BMs, as do the terminators with 1 BM
Lictors appear behind the buildings to the chaos left threatening the mounted plague marines and the decimator.
Terminators appear in the tyranid rear to attack the SC tyrant.
Chaos win ini.
Plague marines attack before they get killed in the transports, assaulting the bugs on the hill.
Zonethrope MW kills and Plague marine, all other make saves. Support fire from bikes helps kill everything apart from one warrior stand which falls back the blitz.


Chaos retain with threatened decimator fails the activation but uses SC reroll, sustaining at the titan. Inflicts 2 DC.
Swarm on the right double out of the crater and shoot at the landraider retinue.
Tyranids retain assaulting landraiders with Broodlord 'stealers.
Support fire from gaunts helps 'nids win by 2 and a single marine stand survives, falling back to the blitz. All 'stealers bar the broodlord die.

Terminators firefight SC tyrant who is killed by chaos sorcerer MW blast, surviving tyrant falls back (BTS secure).
Chaos retain and the raptors firefight unactivated 'stealers, wiping them out.
Titan advances and shoots havoks, killing 2.

Lictors retain and assault havoks. Havok's armour saves are amazing and only 1 stand falls including biotitan support. All lictors are killed.

Bikes assault the titan with support from almost everything. One bike stand dies and the titan takes 2DC and a critical hit roll of 6 (lose regenerate and synapse). It falls back behind the woods.

Biovores hoot at forlorn.
Lictors fail to activate.
Decimator 1 shoots swarm on the right, breaking them.
Exocrines kill one bike.
We decide to stop it there at the end of turn 2 as the tyranids would struggle to stop a 5-0 win to chaos and few fancied making it to the pub before last orders

.
Overall I think Chaos has better dice, in both games but the French list seemed to fair better than the UK one and the lack of spawning made it easier and quicker. However they really need expendable gaunts as breaking the swarms with shooting was very easy.
Regeneration wasn't really a factor but I can imagine it being very irritating. I prefer the uk system of getting more DC.
I'll let MoK suggest the other changes we discussed as he is more familiar with the lists.
