I'd just like to point out that Muslims were modable before SoI and Byzantines were playable before LoR... the idea of a DLC that makes playing as a female more interesting isnt a bad idea. Its not a great one, but not bad. And while its true women didnt have many(if any) rights back then... well Rome was never refounded... Im fairly certain the fatamids never called a jihad for Greece. The Normans won in England. The HRE wasn't some unified super-power. So many things in CK2(some even from the begining) are different than History, so why complain about how women didnt have rights...
Besides, Henry the 1st named his daughter Matilda heir presumptive when his son died and the nobility agreed. Her cousin Stephen of Blois didn't like it and seized the throne, which led to civil war. The civil war wouldn't have happened if Matilda didn't have the right to the throne. Who would have backed her if no-one felt she should be Monarch. While she was never crowned, she was the de facto ruler of England until she signed a treaty that made her son Stephen's heir. Henry the 1st died in 1135. Stephen was a grandson of William the 1st just as Matilda was his granddaughter.
Anyways, if it does become a dlc, you dont have to buy it....
