My name is Walker, and for the past year and a half I have been playing Warhammer with the guys in Ohio led by Sean, or Xaiver on here. But more recently, since many 40k factions don't have codecies, we've been doing infinity escalation leagues. After going through a couple, I feel I have began to understand the basis of the tactics for the game (though with a game like this I can always improve there), but I am pretty unsure about list construction for my faction, Combined Army. I can't decide whether to run the Onyx Sectorial and go without smoke, or to run base CA and go without fire teams. And in general, I'm a little shaky on the best synergies between models either army.
Any advice on this or CA armies as a whole would be greatly appreciated.
