Click here, try not to hyperventilate or panic.
So heres the big changes
1) unstructured or structured. This looks like a quasi-come the apocalypse. We don't know for sure. It looks like bonus's for staying in an FOC, and nothing for breaking it.
So is this good for tournament play? Probably not at all. Will it be banned by exactly all of the tournaments? Yes. Expect every event to post that they only allow structured FOC's. So that will solve this little issue.
2) New ally matrix - we'll have to see how this plays out, as we know nothing more than that it's new.
3) Psyker phrase - This sounds like a cut and paste of the magic phase from fantasy..
4) New missions - This is good. GW is thinking more and probably seeing other games for inspiration. They are a bit random in implementation, but will probably be fun. Expect for tournaments to not come near them though, as they don't make for good missions in an event. As you generally want everyone on roughly the same mission at the same time.
So, no change.
So, basically out of the 4 posted changes
3 - Will either not change the game as events will over-rule them for consistency / standards
1 - CHANGES ALL THE THINGS! But we don't have enough rules for implementation to be upset. However if its anything like fantasy... (which its probably a cut and paste of that).. I expect a lot of upset players.
