Technically you can't do anything if people never want to invite you for reasons intrinsic to the job or the events people are doing (Which tends to rule out Abyssea due to lack of procs, strong cures, and little need for Refresh II). Shuffling us off to the soloist pile doesn't legitimize any activity you'd otherwise partake in since, as an MMO, we should be striving to interact with other players and not be hiding in the corner because we're unwanted for whatever reason. Nobody likes watching a soloist tickle something to death, and it doesn't matter if's a RDM, BST, SMN, or someone else doing it.
