I highly doubt that was the case. They simply had better priorities this time around and it was a fairly pointless sometimes frustrating feature in WoM. The more baggage they drop from WoM the better FE becomes imho

I did not have a problem with the dynasty system at all. The only problem was that it did not seem to have any diplomatic benefit. Either way free heroes and a line of succession was awesome. It was a very entertaining role playing mechanic.

I hope it comes back.  Having a fully working dynasty system was a HUGE boost to the roleplay system.  While I agree there were issues with it, it was good enough that I would have rather had it in the game than not have it.

I really don't see how the dynasty system would work with current gameplay. Besides needing to introduce aging and finding a partner, you'd need to consider factors such as which traits they'll inherit (if any), what level they start at and how will they level late game when they'd conceivably reach adulthood, how dying Sovereigns make leveling to the higher levels almost impossible, etc.

It's better to leave them out, at least for now. Maybe if FE is a success they'll attempt something for the 3rd game.

Well it was kind of odd seeing as how your sovereign didn't retire but he/she could have more children.  From a playertester viewpoint it was a way to get free spellcasting champions.  In the earlier game you had only your sovereign at first.  Then you could share your casting ability by casting the imbue champion spell (for the life of me I can't remember the cost, perhaps it was life/hp in addition to the mana, plus it had a mana upkeep )   Children were innate spell caster and didn't have to do that.   Anyways,  I sure won't miss it.  It wasn't developed enough as stated earlier. 

You really make it sound as an attractive feature ^^

If a dev showed any interest in bringing this back, I would elaborate and make it scientifically accurate as to normal reproduction would be, as well as the distribution of magic amongst the progeny, pregnancy risk/success etc.  I could work the theoretical numbers and whatnot.  I just wouldn't know how to implement this because I am not a programmer/coder.

In essence, it wouldn't be too complicated for the layman, but it would be somewhat accurate and interesting.  It would bring a major aspect back to diplomacy, a deep rpg level, and yes, ready made heros (not too many) with an added risk to the parents (still birth, death during child birth, loss of stats, etc).  It would also create an interesting hierarchy if a faction leader dies as far as inheritance. It could give the game more of a personal touch too.

But I would only work this out if there was interest shown.
