The 0.25 ratio on Defile is deceptive - that's per second. Lay Waste has an 0.4 ratio... unless you hit 1 target, that's 0.8. And a 1 second cooldown.

If you're hitting multiple people with your defile/lay waste you can be laying down 0.65 AP ratio on the enemy team... PER SECOND. Every player. In a 10 second fight, you can lay down 6.5*your AP, then drop the hammer on them for another 550+0.6 AP damage to the entire team. Oh, and if they blow you up? No problem? They have to run because the Defile is still lethal as heck, and the hammer is coming.
