During Blizzard con, the voice actor of Sylvanas, Patty Mattson, read a few of Sylvanas's voice lines during the voice actor panel.

Except some lines we are already familiar with (GREYMANN'S FORCE HOLDS THIS WARDEN TOWER). It appears to me that there are two new voices lines in the new expansion:
The first:
The life blood of Azeroth belongs to the Horde!
The second:
I will grow the rank of forsaken, one way or another.
The first line is expected, the horde and alliance are fighting over the new resources. What interests me is the second (correct me if this is not new), it seems to suggest that Sylvanas will try more radical approach for solving the forsaken's problem. What do u think?
