I'm not disputing that. But the deaths shown mostly focus on deaths on the individual scale. Deaths of soldiers, and all that. What the earlier games didn't do was show deaths for non-combatants (bar the salvage crew). Tarsonis invaded? Green text. Aiur invaded? Some artwork and a cutscene which doesn't show a single dead protoss. UED invasion and occupation of Dominion? Not a single mention of the effect on the civilian population.
WoL has flaws with how it portrays the war, but it at least reaffirms that there's a war going on, and the effects on refugees/civilians (virus, food shortages, conscription, etc.) are actually shown, or if not shown, at least mentioned.
