I...can't say I understand those graphs I'm looking at but I agree with the sentiment being expressed. I get Paradox's point about not having a tension generating nation (even as I think tension is kind of a dumb mechanic that should be removed, given that we now have war support), but at the very least, once they have a few options, they should change it.
Alternatively, or maybe additionally? I think at the start of each game, the game should assign a secret "designated aggressor" flag. That would basically decide who is going to be "The Germany" in that particular game. Not that other nations can't be aggressive even without being assigned (eg, even if USSR is chosen, Germany can still militarize the Rhineland) but this one nation would be guaranteed. It would have much more careful guidance by its AI to help it best utilize its path*, and either always be a major or if it's a minor then it would also be given cheats to a certain point**.
*to avoid situations like Hungary having their Austrian referendum fail because the AI isn't aware of the conditions to help it succeed
**more manpower, more construction speed, etc. Scaling down up to a certain factory count, maybe? So once you have over N factories, you lose it, and the farther below you are, the stronger the bonuses?
