I concur with all of the above with the vanilla game although I´ve never seen the French kick out the English since I´ve started to play first MedMod and then the XL-mod.
In XL 2 new provs in the Iberian penninsula and the adding of the Portugese keeps the Spanish busy. The French still is keen on HRE, HRE still collapses most of the times though, The Danes and the new Swedes and Norwegians are really active and so is the new Bohemians. The Byz and Eggys still team up on the Turks but Byz expansion north is twarthed by the new Cumans, V-Bulgarians, Russians, Lithuanians and Novgorods. The only to main "flaws" is that the French like to kick the HRE-ass rather than the English and that HRE still is unstable.
Some players also like BKB´s mod but I haven´t tried it yet due to lack of time but many recommend it.
