If they just go the easy route and turn CON and THM into BLM and WHM no matter which way they do it there will be massive amounts of raging. I don't want to play WHM so whichever class gets that is essentially wasted SP for me. The only way to do this is to allow CON to become BLM or WHM. To keep things fair (other classes only having one job) they could lock the player on to whichever they choose for 24 hours or whatever so you can't just switch whenever. THM could become anything.
