Ya, Hawkes mother dying in DA2 was honestly my least favorite part because there really wasn't anything you could do to stop it. Almost made me put the game down for a few days out of agitation just on how it was handled. It could have been an awesome moment in the game and a moment to really have Hawke not just have the world work around him.
I stopped playing the game when I found out there is no way to save your mother. The game is just too depressing and too pointless.
