Yeah, agreed, must form spam is pretty annoying. At this point I just ignore them and move on.
Doesn't bother me, I've never even used it, had in incident earlier with someone using it, used talons to deal with it, though not every class has a root?

Mist form is fine, and costs a lot of Magicka anyway so...
Telel is going to humbly point to the much maligned bombard skill from the bow line. It's got some targeting issues (mostly on uneven surfaces) but is a root just like the derp knight's talons and thus useful for pinning fog in its place.
Just shoot them with it until they come out of mist form and let your buddies murder them as they are likely frantically trying to figure out how their game just broke. ^_^
This sublime spew of arrow fun is in fact Khajiit's primary spam skill in PVP and even for CP grinding.
