I am not sure by what you mean by "no follow option". Ghosts can follow other ghosts. If there are 2 or more toons at a spririt healer just have your toons /follow {name of other ghost toon} by typing the command in the chat bar.

Sometime I wipe in instances. Since I use the FTL method any ghost toon can follow another ghost toon from any wow client. If you don't FTL you can make a macro for follow if you like.
