I honestly doubt we'll get a new tank or healer in 4.0. RDM is what I'm mostly expecting, with SAM, DNC, BLU, or their own original Job coming out to compliment it. SAM would surprise me the least as it would be the best pair to spike the hell out of sells. Lore wise I'm sure SAM would show up because the Domans would be ready to take the fight back to the empire, with RDM being a native to Ala Mhingo
BLU and DNC have heavy Thavnarian vibes, so unless we end up dealing with them I doubt we'll see them next expansion.
I would love to see BST, and it would fit from a highland area (Ala mhingo), but I'd call that a DPS in a heartbeat.
I'm banking the next tank/healer will come in 5.0 and will be Garlean based. Magiteck tanking and healing would be interesting and allow them to use their own idea's instead of making older jobs work.
