easiest lvl'ing spec...
As for spec, you can do either Prot or Ret. Ret kills stuff somewhat faster but with Prot you have a lot more survivability so you can handle multiple mobs or solo an elite.
I just leveled my DK from 77 to 83 (he's a gatherer) post cata so his gear was horrid (mainly BC quest greens and some wrath greens, 17k buffed hp at 80 in blood spec) and it took forever to kill stuff in Vashj'ir in blood spec, but it was doable. In frost spec it was suicide. Now he's got cata greens and just slaughtering in unholy spec (pet is nice for mining). For elites I swap into blood and just own.
Doing a non geared pally will be the same way. You can survive the hard stuff in prot just to get some gear to slaughter fast in ret. Once geared you can solo faster as ret, and handling multiple mobs is rarely a problem.
the nice thing too is, i can now hold aggro with cc in dungeons, whereas before, it didnt matter how hard i dps'd, i would have to fight for cc.
