WarCraft has always been character driven. And characters love. It’s a huge motivation for the vast majority of characters to the point that it’s absence as a motivation of some sort is often a plot point unto itself.
There are nations and armies and war in the setting, but the focus has always been more personal than that. I swear, some people just read a wiki summary of the story and think that’s an equivalent experience to actually going through it with the characters as written.
