Yeah I'll get right to using those CBs that can't be used unless a country is bordering me with a different religion or government form and only after I have an idea group I may or may not really need. Skirting the rules of the game because they are applied poorly and illogically isn't strategy and has nothing to do with whether cascading alliances make sense or are a good game mechanic.
What? really? The CBs are what makes the idea set so good... And its because the CBs are so good, that they require being bordered nations with fixed parameters, else you'd still have the "one CB fits all" issue that is what the OP seemed to think was the case.
NO! One cb does not fit them all, There is 100% a reason that conquest sucks so bad... because it's free. Anyone can use it at any time.
Again I'm not against more information, but the imformation IS THERE! As any experienced Paradox gamer knows, it's all in plain text in the game files. Most seasoned players opened those files to have a look before even starting the game. I am no exception, although it was a very precursory glance.
There will not be a change to the casscading alliances, it is WAD. Nor should it be changed. It's up to you, the player, to actually pay attention to the details. It's all about the details. I know exactly what's going on because I pay attention to those details... "Hey Opem, be careful you dont step in the bullshxt."
The game can be as complicated as you wish, or as simple. For the best experience, and fullest game, paying attention to alliances, waiting for the right moment to strike, using insults, or allowing relations to sink, so you get insulted, can add a whole new dynamic you've been missing, if all you've been doing was playing the simple game of "fabricate, dow" which by the way, is still a viable way to play the game.
I commend paradox for adding the extra level of detail for those who wish to pursue it. Yet the GnuB scrub doesnt have to be so daunted on his first or seventh game.
