The Dorne storyline would be more powerful in the source than the show. They didn't do Dorne any favors in the show and it would probably end in typical GRRM fashion where Doran is finally ready to spin the wheels of his master plan he was spinning but then gets cut down by the Sand Snakes. That is pretty much how all the major deaths occur in this show (Jon and Robb being prime examples.) I don't recall in the show Doran even really revealing he was working behind the scenes on forging alliances to ensure victory in the coming war.
And while I'm on a drunk rant, fuck dorne. Stupid motherfucker got a better tv storyline than he deserved.
Keep seeing this bullshit "masterplan" nonsense like it wasn't some bs retcon on grrms part just to fill the gap.
Doran was a fucking weak ass retard. His plan was fucking retarded and had already failed.
People give too much credit to that stupid fucking revisionist history speech he gives his daughter like that makes up for his failings.
Dorans "masterplan" according to the books:
Oh shit they killed my sister and my niece/nephew, lemme;
Banish the only motherfucker in dorne with any balls (his brother oberyn)
Forge a secret marriage pact between arianne and viserys, except never inform arianne or viserys
Allow the targ prince which I've wagered everything on to wander essos as a beggar with no support whatsoever, constantly under threat of assassination by Robert baratheon.
Wait 17 fucking years
Oh shit he died. Still never inform my own daughter and heir to my throne of my plan (because grrm just created this shit on the fly, it was never part of the original story)
Meanwhile my daughter and heir has gone well past longing for my approval to resentment to outright plotting against me, thinking im trying to deny her birthright.
Oh yeah, pivot to another shitfuck plan of sending my immature fugly 18 yo son with the charisma of a newt to try and woo the most beautiful woman in the world, who's also a queen and conqueror and has 3 full grown dragons and a fucking army, while offering nothing but the loyalty of the weakest of the seven kingdoms in return.
Wait again for no reason.
Unbeknownst to him of course his shit son is already extra crispy kfc style and nothing is coming, except his daughters plan to say fuck doran and rally her own war against the crown. Doran is a bernie fucking sanders of useless fucking cuckness who accomplishes nothing. so the tv show changes his daughter from ruining his shit plans to his sister in law. Big fucking deal. end result is the same.
Doran's "masterplan" is somewhere between "the best revenge is a life well lived" and "maybe my kids will outlive my enemies kids so I win", except his life is one of agony and regret, suffering gout while his enemies live full, complete lives of power and prestige. Also his kids are dying faster than tywins so he doesn't even "win" at that.
His plan is like my plan to marry and impregnate scarjo about 6 times. We both sit around and wait for it to happen on its own and if it doesn't, oh well didn't really wanna do that anyway
