A Wars of the Roses timeline results ins Yorkist Victory like 95% of the time. There have been great timelines with that happening, but like, changing it up with an alternative Lancastrian victory (Hollands or Beaufort or even main line Lancastrians getting the throne) every now and again wouldn’t hurt.
I think this is a case of "backward projection" where people project GOT's Stark attitudes onto the Yorks, in the same way that Lannisters are supposed to be Lancasters. They can usually be spotted because the House of York is portrayed as being immensely adored, honest and loyal, whose members are 100% pure and honest...while the Lancastrians are portrayed as greedy bastards who are hated by everyone, completely lacking in honor, and nothing would delight his subjects more than to get rid of them.
Clichés I've seen.
-Huey Long always has a disproportionate importance and political weight, even if the United States does not exist and Louisiana is French.
-The United States will always end in a war against Japan, in which Japan will be defeated.
-China and Japan always end up at war in the 1930s, even if China and Japan as we know them in OTL don't exist.
-Korea, Hungary and Poland only exist so that the neighbors have a place to fight.
-Any territory that becomes independent will necessarily be much more prosperous and rich than it ever was in OTL remaining united. Bonus points if they absolutely ruin the country they split from in the process.
-The smallest countries always become very advanced democratic and progressive nations, while the largest become horrible autocratic and backward tyrannies. The only exception is United States, of course.
-Regardless of how horribly bad the TTL recording of the Republics is, from 1780 extremely violent republican revolutions will begin to break out all over the world.
-Despite the fact that, as a consequence of the previous point, in TTL, Republic is synonymous with excessive violence, chaos, destruction, tyranny and death, people will still love the idea of forming republican governments and will focus all their efforts on this idea .
"Bad people make bad presidents." When someone who is a bad person comes to power, he immediately starts making stupid and evil decisions in such a way that it seems that he is deliberately trying to sabotage his own country to leave it in the worst possible situation.
"If you're bad, bad things happen to you." Unless history is going to see to what extent the world can become horrible, the bad president of the previous point begins to suffer completely random misfortunes before 2 years, or the population decides that it is time to organize one of those republican revolutions before mentioned to remove him from power.
-There is no 50% approval rating. The population comes in two flavors. 1, absolutely adores his ruler and will fully support him even if, based on the knowledge of the time, he is making completely meaningless decisions. 2, THE ENTIRE population ABSOLUTELY hates their ruler and are so desperate to get rid of him that, if they were the Republic of Poland, they would happily welcome Hitler's Third Reich as a liberation to get rid of the President of Poland.
-There will always be a crisis modeled on the Great Depression, sometimes with elements of the 2008 crisis, regardless of the economic policy of that universe.
-Of course, since most authors overestimate the economy to the extreme, this means that before three months the Government will fall into the most absolute anarchy, will suffer a civil war or a communist revolution completely out of the blue, or all at once , and you will expect me to believe that this is a direct consequence of the economic crisis.
-The Anglosphere is always well and in excellent health, even if they have had to fight much more devastating wars than OTL. Needless to say, the Anglosphere is vastly stronger, richer and more integrated than OTL, and the other members are more than happy to heed advice from London.
