When I started to play WH40k, I chose DA as my chapter cause I liked their colors and loved their fluff. However, i'm a competitve player, and like to win as much as having fun. With the new SM codex here, i'm seeing some much new stuff that i'm loving and playtesting, makes me wonder if i should finish painting my DA stuff. My biggest issue is the question of: "Do we get to use the new stuff in the SM codex, or have to follow our codex to the T?" For example: Chapter masters now get an orbital bombardment but Azrael does not. Whirlwinds get to chose which missile they fire when shooting, while DA whirlwinds have to chose at the start of game which missile they can fire. Sternguard, Vanguard, Thunderfire, etc..... do DA even get to field them? There is more than that but the biggest thing is, why play a divergance chapter now if you can field newer, better units playing vanilla. If someone knows if theres a rule or FAQ or errata somewhere that says any chapter can use any standard codex stuff, please please enlighten me, but as of right now i'm lost in my chapter selection and i'm concidering UM now due the fact they get the most love of all chapters, and through that the most special character choices.
