Just read the
FAQ.
Glad they acknowledge 3 different forms of play: Open play, Narrative play and Matched play.
I like dabbling in all 3 methods so I can approve readily.
I have no problem with old codexes are not compatible with the new rules.
Not to say they are still not useful for the various fluff and flavor.
Things have been patched so much that I hate to say a new re-write was overdue.
I hope they got some smart folk on-line to ensure a clean ruleset to play to.
The stories continue, if the new rules allow us to play out the various stories of
40k I think there will be much happiness with this.
Having a balanced element for competitive play will make me a VERY happy person.
Tournaments are SO much more fun with some core balancing in the rule-set.
Heck, I was ready to jump down the Shadow War Armageddon rabbit hole and say goodbye to normal
40k.
Now they go do this!
