shade shift is solely for enemies, teleportation is a utility mobility spell, as is netherswap, used more for setting up a fight to your liking (manipulating friend and foe) instead of ending it with damage, though barrelmancy is still a thing. things like spread your wings, phoenix dive, cloak and dagger, and tactical retreat are purely mobility spells designed around re positioning to avoid or prepare a strike. Planar gateway is a utility spell that allows ease of movement rather than being a movement spell itself. lastly, chameleon skin supersedes them them all because cloaking technology.
Shadow Mages for lyfe.
kidding aside, there is no such thing as too much mobility. I'm running a ranger build with all 4 mobility spells, and it works a hell of a lot better than i thought it would. cant kill whats always out of reach, with play dead and chameleon falling in as back up.
