The only time I've taken out ward with Landfall is when I was inside and the titan was most likely running weapons. Which means it dropped because I killed the titan, not the bubble. I can drop Landfall directly on top of a blade dancer, and still be killed by it before I'm able to do enough damage between Landfall and the lightning to kill him. You can shut down a blade with 1 golden gun shot, yet I'm pretty sure it takes 2 to kill a bubble. And there's no way in hell Landfall does 2 gg worth of damage. It doesn't even do close to 1 gg.
