1-I think the game developers mixed up Islamic faiths sectors, It should be sunni and shia only, like for Christianity is Catholic, protestant, orthodoxy.
other sectors are school of thoughts in islam (mazaheb) are all inside sunni or shia, i mean it shouldn't be another faith, i hope there is a fix or mode on that matter for historical and religious accuracy, if there is any other faith in islamic faith can be like events or temporarily faiths (Cults)
or groups (outlaws,rebel) bandits ect...

+ other suggestion after reading the (Detailed Breakdown of Changes) of the mode
2- now my family children are not gonna take traits granted from their parents 100% , so i have another alternative to make it more realistic and historical , why not we make the heir of mine and my kids in general is thought by 2-5 teachers in condition the that all teachers are in the same court to make it more guaranteed traits and make them more experienced by them and plus if i made the hair a vassal in a young age and let him go govern and his teachers acts like regents ,in the end he will be more capable ruler in the future.

3-now assassinations will become happening more for me or my heir, can we we have like royal guards or something like that and will be in a hand of me or one of my trusted vassals for more protection

4- now moving big armies takes times,supplies,cost for big empires, is there a possibility if i can raise a portion of my levies and man at arms and keep the rest unraised.

and thanks for reading, i hope to know what the developers can do and don't , pros and cons please
