I was playing today and I saw a very organized zerg group at Nikel and I started using my rune cage stun as usual and when one or two of them died their whole group collapsed. And they kept coming back to Nikel many times to get a taste of rune cage. It's funny when they can't get back to their organized group to get a heal. Runge cage is getting a nerf today but I think it's still going to be effective in gameplay.
