Regular troops have little to no choices, characters, chosen, AC's have a lot of choices and can really be nasty.// What's your opinion on the choices/flexibilty/equipment,etc. of the Thousand Sons?
Certainly not the easiest army to start with.
Depends on the legion I play. When fielding my Emperors Children I often field squads of 6 since thats the favored numbers. Otherwise 8 seems a more solid number. CC squads often 10 man strong.// How large do you usually field chaos marine squads?
Probably bikers. The increased toughnes and ability to turbo boost makes them much more survivable. Biggest problem with raptors is that they are no more survival than your regular marine. All in all, raptors are more difficult to use.// In your opinion, what units do you think are more effective in general: Raptors or Bikers?
