I manage to catch a spouse and try out on dynasty. Of 4 children born, i notice that their stats are are worse than most champions I pick up wandering in my kingdom.
I take the ave stats points in either str/int/cha/con/agi to be 10 as per starting game
First child - 12str/7agi/5int/5cha/9con
Second child - 10str/1agi/7int/5cha/7con
Third child - cant remember but has 3 stats 5 and below
Fourth child - cant remember but also has 3 stats 5 and below
I really do hope that this is not intentional and get boosted abit to 7 - 9 range before actual launch
