Hope they patch the anti-estus bombs to ignore rolling invincibility frames

Literally every single invader I've encountered so far just hides behind every group of enemy they can find and takes pot shots at you while you're distracted, and if you hit them even once they start rolling around hundreds of thousands of times until they get enough space to drink estus. I've tried using the anti-estus throwable but it's only really possible to land it when they're, you know, drinking estus... Kind of defeats the point...
