How much +hit and +exp is too low to go as Prot as far as being able to keep threat in something like heroics? I don't raid, so I know I don't have to hit the lvl 88 numbers, but I was just curious. As it stands right now I'm looking at 8% or so hit (draenei) and 20 expertise (with SoT glyphed and active).
Any help would be much appreciated.
