I would only find it fun if i sucked at tribes and got tired of getting my ass pounded on pubs. Even then, i would probbly go to some modded server before playing bootcamp.
You basicly do a few things, like shoot bots that fly in highly predictable paths, "MA training" and some other stupid things. Only usefull if you just started playing tribes and just need to know how to accualy aim and hit things.
