World of warcraft best cl for cataclysm?

since the cataclysm expansion is coming out soon i need help on making a new character. what cl would be best for when i reach level 80 raids and solo-ing and cataclysm features? im thinking either a druid, paladin, warlock, priest, or hunter. if one of those is good please tell me why oh and if theres one thats better than these please tell me why also. thanks!
