Until last week, I didn't experienced the Fatimids invading the Byzantine Empire, because I played either games started with a different version of the game, at a different startdate or with mods. I just tried a game as one of the venetian families and just when I discovered that the new DLC didn't prevent at all republics to expand by conquering Italy in few years, I saw the dreaded fiction becoming truth. Fatimids indeed invaded the ERE to take Greece, but left it totally untouched on the east side. I will say as many said before me : this makes no sense and it totally broke my immersion, already shakened by the very agressive republics I was dealing with when I though trade would be more subtle.
So, I humbly suggest to the developpers an idea that could be a potential fix to this problem. Make holy wars CB impossible to use if you are not bordering the land you mean to take. You would still have other CBs, of course, but this one, aiming at entire kingdoms, would be forbidden, for christian and muslims alike. What would you think of this, until we have a proper navy? While making an invasion of Ireland by muslims less likely, and also an invasion of North Africa by catholic less likely, it could stop the too early desagregation of the ERE.
