I have recently spent many hours playing as muslim rulers and I absolutely love their ability to expand and conquer quickly. But something that just outright ruins the experience for me is when a vassal out of nowhere launches an invasion on me [playing as the Seljuk dynasty]. I wouldn't matter much, if not for the fact that he was granted 50,000 goddamned troops immediately! They just spawn out of thin air. At the time I had a total levy size of 37,000 men; plus the 10,000 mercenaries I was able to recruit, but I still stood no chance of winning as he quickly stormed and captured my domains. He ultimately won and was declared the new sultan and I was imprisoned and downgraded to duke [beylerbey] of something irrelevant. This made me ragequit and write this thread. Why is this implemented and how is a one-county vassal given that oppurtunity? Does this happen while playing Christian rulers? And just for the record I am not using any mods. Please share your input.
