Bump. Was looking into research on Rogue poisons when I came across this.
Glimmers removing run speed change immunity should also make them Rogue slowable (its currently blocked with a run speed change immunity message from the root component); I found a near-era comment asserting this was possible here:
https://thesafehouse.org/forums/foru...t-by-the-rogue
Its out of era and references another thread that I haven't been able to find, so its relatively weak evidence by itself. It is, however, another reference point that these were probably snareable.
