#1-keep the zerkers in the Land Raider. If they disembark from a rhino, they cant assault, and that kind of defeats their purpose. The Assault Ramp on the Land Raider allows them to charge when they disembark. Also, the LR is better armored, upping their survivability.
#2-Yes 6 man squads are not going to last, especially if they don't have any kind of armor to actually get into the fight. I would place them in rhinos and zip them around the table. It's especially good if you're playing objective based missions, as they can move 12" and contest an objective.
#3- I've never had that much luck with with the Defiler. A BS 3 is kinda trash, especially when firing the main battle cannon. (but i normally have terrible luck with scatter die). I would drop it and take either some Termies if you can or get either a Predator or Vindicator for your crowd control/tank pop, depending on what you were going for with the Defiler. I happen to like Oblits, even though they usually are a primary target by the second turn theyre in.
#4- Dreadnoughts tend to be more trouble than they are worth. I would recommend them if they could take the same armaments as Imperial Space Marines, but their selection is limited, and the Fire Frenzy rule, even if you put it next to the rhino is still a liability, especially if the rhino gets popped and the troops are exposed.
#5 - Your Chosen are fine the way they are, for what they're being used for (speedy tank pop, I assume?) I dont have the 'dex with me, but I think they have 'scout' special rule, correct? If so,ditch the rhino and place them as close to a tank as possible.
#6- I honestly don't use Lesser Daemons enough to attest to their functionality, but for objective based games, nothing holds objectives better than Plague Marines. With their enhanced toughness, they can shrug off most las/bolter/shuriken attacks. But if lesser daemons are your thing, then do it, man.
#7- Every time I've used a greater daemon, it usually hasn't lasted longer than turn 2, even with 2 other daemon princes running around. I would honestly drop the greater Daemon and get something else for it.
THe lash tactic is good, however relying on the template weapon of the Defiler is iffy. I usually lash them near Termies or Zerkers and thrash them that way (as I mentioned before, the Scatter Dice Gods absolutely hate me) I am also going to advocate a Chaos Lord in Termie Armor with a Daemon Weapon added to your Zerkers. I have this unit and it tears everything up on the board wholesale.
Lastly, Im going to say that I prefer Terminators to be on the board in some way shape or form. Nothing infuriates a player more than seeing 6-8 Termies deep striking behind their lines and blasting tank/infantry pell mell. Add a chaos icon to your units' sergeants or the Chaos Lord (if you take it) and you have a hell of a left-right knockout combo when they come in.
Hope this helped. good luck and good gaming.
