This actually makes me think of my idea for RDM/MST(mystic knight) coming from Fencer class: http://forum.square-enix.com/ffxiv/t...night-Proposal

I basically make Fencer a DPS debuffer that turns into RDM for melee mage DPS or MST for tanking. MST makes a better tank in my opinion than RDM but again just my opinion. Please give a look if you haven't and like it so SE might see and get some ideas
