Last time I try to bring Glut with me to the Arcane, he actually mention he will only follow you in the underdark and hate sunlight, then teleport back to colony.
I am not sure about if raised dead will follow because last time I don't have any yet when I reach arcane tower.
Regarding jump/fly follow, totally agree that should be auto unless the individual character(s) can't follow, like due to not enough strength to jump the distant.
