Which cl/spec should I use in cataclysm? If the ones Iis aren't right please reccomend a good cl/spec?

I quit WOTLK about 2-3 months into it. I had a level 80 warrior, 80 rogue, 80 paladin, and a 72 hunter. My warrior was arms/fury, rogue was combat/asination, my paladin was protection/retribution, and my hunter was beast mastery/survival. All my level 80s were geared for 25 mans and my paladin was geared for 40 mans. I could pull around 2.5 - 2.8k with my warrior, 2.6 - 2.9k with my rogue, and 2.8 - 3.1k depending on what kind of day I was having. Since I haven't been on WoW in awhile I was wondering which certain cl/spec combos were dominant in the dps category. Not to worried about tanking until I get back into playing.
