Some focus trees, especially older ones but also some fairly recent ones, don't really know how to deal with AH scenarios, even ones that have their own national focus trees. I know Paradox isn't eager to partially revisit older focus trees outside of big patches, but some of these have some pretty significant effect on gameplay.
For instance, the Purge the Kodoha Faction branch stops halfway if Germany isn't fascist. There's no bypass on the Tripartite Act if Germany isn't fascist, it just shuts off the rest of this branch, including the part . And since this branch is chosen at the game start and locks out the other ones, it can't really be undone or compensated for either. It doesn't happen a lot with historical focuses off, but playing as non-fascist Germany and having this happen is still quite weird. IT shuts Japan out of being able to attack the Phillipines, Indo-China and South-East Asia for no apparent reason.
Similarly, other focuses that are reliant on hard truths (like Germany being fascist) don't quite work either. Australia and South Africa can't pick the British Empire-oriented branches when Germany isn't fascist, since they both require the Purge the Rhineland focus to be completed; so if Germany turns non-fascist, Australia and South Africa can't do anything but go Fascist or Communist. And so on with things like the American focus tree, which is really dependent on everyone having just the right ideology. Even the DoD focuses (and related events) need some work in some places, since they're pretty reliant on a Fascist Germany too.
Now, much of this may be intentional, but there's just enough wonkiness in many of the game's national focus trees that it's hard to determine what is intentional and what isn't. As it stands now though, it feels like AH options are only partially implemented. I know it's hard to account for every eventuality with focus trees, but a little more flexibility can't hurt.
