As I'd used history class to get more regimes - I ended with 11 majors and run into such issue. Game seem to generate "bordering" event for each major you're bordering. But such events are have only two options AND affect completely unrelated profiles, so I'm slowly get overwhelmed by those events ruining my government.
First - it's very stupid that our government is suffering as result of diplomatic relationship. Why I can't send my foreign director to delay this in endless negotiation (possibly with skill check & huge relationship penalties if fail)?
Second - game ALREADY have similar events linked with Councils, but in that case we HAVE third option. Yes, third option is purely negative one but allow to avoid HUGE spikes of undesired ethic (see next post with image of such event).
Third - as result you're penalized for bordering majors as with current ethic influence system there is quite high chance that BOTH ethics will be opposite to your own - with those events statistically is 66.(6)% that you will have TWO opposite ethic as a possible choice (well, pure calculation based on assumption that game have equal amount of events for every possible ethic combination, so real situation may be even worse).
IMHO it's too much (especially as it seems that every major independently proc it's own diplomatic event).
