I am an old hand, last played in 2nd and 3rd edition (Chaos then too) and only now returning to 7th. I know I want to play Chaos again, because the army has always resonated with me, I'm just not sure which Chaos direction I want. I've done some research (been following things for a while now as I dabbled in other games), but I'm still "Chaos Undecided" as it were
I've basically narrowed down my choices to either doing Khorne Daemonkin or a CSM-focused force likely using the new Traitor's Hate book, in which case I am unsure of choice of Legion (despite them not having rules anymore). I plan to play casual/narrative so I'm not too concerned about competitive list building, since I want to focus on actual Chaos Marines not daemons and cultists. I've tried to compile a list of pros/cons for each:
Khorne DaemonkinPROS:
* Cool fluff, allows for literally fighting anyone else in the game including other Chaos or KDK armies
* Rules seem to gel really well together, better than normal CSM (That boon chart looks stupid as hell)
* Daemons can be used for other ventures too (I'm interested in AoS)
* Khorne is the "favorite" Chaos God
* Seems fairly powerful, even without doing the "Release the Hounds!" list focused around Gorepacks
CONS:
* Khorne theme can get a little bland
* Painting red can get annoying (although I'm fairly good at it)
* Seems like it's a one-off Codex so has me a little concerned about support in future editions
CSM w/Traitor's HatePROS:
* Traitor's Hate seems to add some viability to having CSM-focused armies
* "Core" army (power notwithstanding) so always will have a place in the game
CONS:
* CSM by itself, even with Traitor's Hate, still seems weak overall
* Fluff-wise, would have less reasons to fight like other Chaos armies
* Likely would be more expensive to buy overall (more vehicles and such)
I'm honestly leaning a bit towards KDK because they seem more fun and more focused than the hodgepodge of stuff that is regular Chaos, and also because as a fluff player the idea of an army that really embraces GW's pushing "warbands" on Chaos over Legions is appealing, but part of me wants to pick a traitor Legion (which would be one of Black Legion, Iron Warriors or Word Bearers since those are my favorites) and that would entail CSM itself.
Any suggestions for why you play what you do, and which of them is more fun/better to play with in the current state of the game?
