I would love to see a new healer for the next round, but I can very easily see them citing balance issues again as a reason for not adding one, and leaving just the three we have for eternity. I can see a Rune Fencer happening if they do the inverse of the RDM style. Have most of its rotation be melee enchanted sword attacks and a short burst of magic attacks. Who knows what will happen, and its a little less than two years away so plenty of time for speculation.
