Q: What's my MT spec?
A: Basic tanking talents:

Q: So where do I put the three Prot points?
A: Good options: Divine Sacrifice + Divine Guardian are quite good utility. Reckoning provides moderately OK TPS.
A: Meh options: Imp HoJ is very occasionally useful in PvE. Divinity works, but isn't real useful for a tank (or anyone, really).
A: Bad options: Stoicism and Guardian's Favour are PvP talents.
