Arthas committed patricide and killed his father Terenas Menethil.
While this is true, we never found out what exactly happened to his mother or sister, his mother is assumed dead now, which is understandable. His sister is another story left for that thread.http://us.battle.net/wow/en/forum/topic/8198732876
Cairne Bloodhoof was murdered which left his son Baine to deal with fallout and pick up the pieces.
Which is good. But his mother also died early on and I actually had to Google Baine to find out what his mother's name was.
Anduin didn't just lose his mother. He had to suffer through a period in which his father was lost to him and then his surrogate father ended up becoming the Lich King.
Yes his mother died early on before we could even really know her character. All I know is she gave birth and died in the riots.
Thrall didn't just lose his mother, he lost his father too and his adoptive father wasn't a picture of kindness. He enslaved him and tried to kill him. That will cause some father issues if nothing else will.
Again, showing how his mother died never allowing for a relationship to develop in this game between a mother and her child.
Garrosh was abandoned and his father wasn't exactly around to raise him, though he was an influence on him. I'm sure you recall Grom Hellscream.
Source? Never heard this before and it's not on his Wowpedia and wowiki pages. So for all we know you could be making this up. Either way, no relationship with his mother.
Leyara lost her daughter and her husband was murdered as well. Her relationship with her father-in-law didn't exactly result in warm and fuzzy quality time together either unfortunately.
One example of us see a mother's relationship with their child and how losing a child can affect you. But, we don't get to see any character develop into an adult and become important part of the lore having only being raised with a mother's influence.
Vereesa (Windrunner) is raising twins alone now that her husband Rhonin was killed in Theramore. She's also dealing with a few sister issues.
The first one we get to "see." But really, the children have only been mentioned very few times, both in books. One time when they were being born in the War of the Ancients trilogy and the other at their father's funeral. We have yet to see them in game which leads me to believe they won't play any important role.
Moira (Thaurissan) is dealing with the death of her husband and her father turning to diamond, while being a part of a new leadership.She's dealing with something many working mothers are familiar with in balancing her dedication to her son and the council I'm sure.
FINALLY! This is what I've been saying. Moira is the first mother we may actually see in this game raise their child without the father's influence. This is what I've been trying to say. We have seen plenty of characters throughout Warcraft being raised with only their father's to influence them. Baby Thaurissan will be the first without a father and only a mother, if we ever see him grow up in Warcraft, none of us know when Blizzard will stop with the Warcraft franchise.
Suna Silentstrike is another one who has lost her husband to tragedy.
As I was trying to say in my original post, this is not about male character's losing their wife, or female character's losing their husband. It's about how no character in this game (as of today, March 21, 2013) has been raised with only their mother's influence to carve the character they will evolve into. They've either been raise by a father, both parents or no parents.
