Chill and slow are my debuffs, yes. I didn’t think about the log file last night, as I went to bed right after I posted this, but it seems that I don’t have the information.
I’ve seen information about certain debuffs causing him to not perform certain abilities, though I’ve not seen him effectively refuse to return for :20-:25.
Full disclosure, I also have shock, though I doubt that’s a factor since it’s a debuff to defenses rather than movement. Blind is in there too, though it’s more incidental with Smoke Bomb.
