Slaanesh is the weakest chaos god, man. Slaaneshi sometimes try to claim all actions fit under excess (same with Tzeentchians and change) but "excess" generally refers to "Excess of otherwise pleasurable activity taken to unhealthy levels," not "excessive amounts of war, paperwork, rocks, empty space, order, punching, etc."
One must also remember that the movement of souls into the Immaterium is a prime interest of the chaos gods.
And Nurgle isn't the Chaos God of Death, silly.
If I had to rate the chaos gods from strongest to weakest, it'd be Khorne first, because more deaths of sapient beings generally are thought to happen through war than decay (see: Orks, who are immortal until killed), Tzeentch second (Death is a form of change), Nurgle third (his model of death isn't quite as prevalent as on our world), and Slaanesh last (his portfolio is arguably the least destructive).
