for me personally, the flaming arm and circles get me. for the arm i usually rotate the camera past where he appears before he shows up and by the time the camera pans around again he's already charging through the area. i suffer from this in any fight where this is a thing (like nidhogg ex) i could follow the other people but half of them are usually running the wrong way anyways. as for the red circles i usually find myself in a cluster of them and even trying to sprint out is usually futile because someone ends up running the same way as i do just a little ahead of me causing the 2nd circle to appear under me as i run. generally just bad luck.
