Arbitor's flame blast spawned off-screen

I just now killed the Arbitor and died quite a few times to one of the flame blast balls that spawned completely outside of my screen. The programming for their spawning patterns could use some improvements.

Also, the slowdown animation at the end of the dodgeroll stun-locked me right on the edge of the blast, which was terrible. I think GGG need to pick just one of the two: a normal roll or a fat roll. What we have right now is a weird hybrid of normal roll, then it transitions into a fat roll at the end, which feels really weird.
