Yes i do.
If you were to work on 3 systems your Fac is present in, and then on the next tick you find yourself in boom, how would you know who is in boom and who isn't if it weren't a faction bucket as opposed to a system bucket.
If it was system, your faction could be in boom in A but its says your in boom in B also. But you think it is B that's in boom. So you trade like crazy to fill the bucket in B, but what your actually doing is pushing B into boom, but you can't see it. So now A and B are in boom, and you don't know it.
It makes no sense to advertise boom faction wide, but it actually be system specific. Wars etc aren't this way, so why would boom and expansion be.
Another reason I believe this is news of war. I have noticed when my fac enters War, I get news reports in other systems my faction is present in of the war, but erroneously telling me that it is that system in war. News feeds appear in this case to be faction specific and not system specific, although the state is.
I could be wrong, and in being wrong it may account for the reports of 'endless boom' periods if it is system specific and people are feeding the wrong pot.
good reasoning, let me try the opposite
- civil-wars have effects faction-wide, but can only be won in the system where they origin. even if you have the same factions in two systems, both showing civil-war, you can't win the civil war in another system
- let us assume there is a state-bucket for each faction per system. if a state goes active, this bucket is emptied (or need to be emptied). e.g. when the state finishes or runs out, it starts again with zero. if you for exampel finishes boom, state can go recovering directly. you'll still have the cooldown.
- how can the system, where the state origins, be found? via POI - like CZ.
