Pretty much what you're being told, advertise yourself. But to cut the crap and get straight to it, you need to prove your worth to those in a static. Show people you can play, and can play well. Nobody wants a dead weight DPS, regardless of which job it is. If it means changing, you should. Being flexible in a static helps a lot!

I used to MT in mine and switched to MNK because FCoB really is MNK friendly, plus I do reasonably good DPS.
