today I have planned second CAV game in my life (YAY!
)
hmmm... my opponent had to change sunday plans so there was no gaming (YAY-not

)
I disagree. My 2000 points looks very similar to yours. I love my Centurion - it is in every force I take. I would take it over an Ogre or Rhino any day. Instead of the centipede, I take a few gunships. The only thing I would suggest is adding in a recon to boost the Centurion. It has great range and good armor degradation. In cover, the thing is very hard to knock out. Practice is the key. In CAV, things need to work together - concentrate on targets, and use ECM / EST support whenever you can..
about centurion I meant it costs lots of points - it's very powerful, has maximum DT but against heavy-hitters it can use only double piercing weapon, whereas ogre carries 3x piercing weapon system! that's vary handy against line on advancing despot tanks
maybe I'll appreciate full value of centurion when we start playing games exceeding 2000pts limit
The Poltergeists are good for their role in the game - pretty cheap, and hard to hurt. If you are not facing any soft targets, or never get the shot in against them, then yeah - they aren't that great.
I've found them perfect against opposing recon vehicles - but I have to agree: if there're no
soft targets poltergeists can probably only distract enemy's attention from my other forces
Duellist are necessary. Worth repeating :) And, you can either kit-bash or wait (hopefully out soon) for the Crusader. Heavy Recon CAV......
I think I'd rather start with duelists - at the very early stage of engagement in CAV I don't feel comfortable with converting stuff... yet
btw - I've noticed most armies are based on CAVs, not "classic" tools of warfare like tanks, apcs and infantry... is this maybe only my point of view or maybe tanks and infantry are not that functional? maybe just underrated?
