Hi!
I get your reasoning when it comes to the CC units possibly being too small, but I'm testing them out in accordance with the MSU principle, which I've come to strongly believe in.
I used to take 10-man Banshees and Scorpion squads back in the day, I'll admit.
Nowadays, however, I've come to realize that if I buy the additional models for the squads, their durability will not increase relative to how much threat they will generate. While I know that a 10-man strong unit will naturally live longer in theory, with more models being alive once you get to charge, it also means, in practice that they will attract even more unwanted attention. A 10-man unit running with 5-man units means my opponent will never have to doubt where to pool his firepower. It's all about target saturation.
Even a full Scorpion unit with a 2+ cover save isn't all that hard to kill if you put your mind to it. A 5-man squad, however, might make your opponent reconsider if it's really worth pooling all that firepower into it.
Then there's another problem: say your 10-man unit survives - it can still only assault one unit at a time, but now you've put a lot more points into that one unit, for basically the same result. It would then be better to take 2 5 man squads. At least, that's the general idea of MSU.
Again, though, I haven't tested it on CC infantry yet, but it works for ranged units to be sure.
That being said, I personally believe the squads actually need to be bigger, just like you say, but I'm eager to see how 2 small squads works compared to one full. I didn't have the points for 2 10 man-squads, you see. I wanted both Scorpions and Banshees because the idea is to use those units again (it's been a long time for me). That's why you see 1 5-man Banshee unit and 1 5-man Scorpion unit in there, and not 2 5-man units of the same CC Aspect.
As to dropping the Reapers: they are simply too powerful to exclude.
The reason I use the Warhost is to make use of the guaranteed 6" run distance rule for my CC units.
Otherwise an ordinary CAD certainly is the way to go.
My main list (the one I've had such great success with, and from which the list above is derived) is as follows:
Combined Arms Detachment: 1223pHQ: 235p- Autarch Skyrunner w Laser lance and Banshee mask (joins the Shining Spears)
- Farseer Skyrunner w The Spirit Stone of Anath'lan and Singing spear (joins the Shining Spears)
Troops: 243p- 3x3 Windriders, all with Scatter lasers
Heavy Support: 435p- 1 Falcon Squadron, 3 Falcons w Scatter lasers, Shuriken cannons and Spirit stones (Deep Strikes as per the Cloudstrike rule)
Lord of War: 310p- 1 Wraithknight w 1 Scatter laser (and whatever main weapon combo I deem necessary)
Formation Detachment: 774pAspect host: 419p- 2x5 Reapers w Exarch w Starshot missiles (embarked on Falcons)
- 4 Reapers w Exarch w Starshot missiles (embarked on a Falcon)
Aspect host: 355p- 5 Shining Spears w Exarch w Star lance (Outflanks)
- 2x5 Spiders w Exarch (One or both units Deep Strike, depending on where they are needed)
For a
total of 1997p
