Best class(es) to farm old dungeons/raids?

[chiroguy]

Hey guys, so my rogue is now level 80 and approaching 3k gs. I've mainly just been questing, but am starting to be interested in soloing dungeons and raids. I'd like to decide on a class before I invest more time on this toon in farming Emblems for gear.

Can you give me the top 3 or 5 classes/specs that are good at soloing that content, and why?

Thanks :)

Ranged classes don't make the cut since you can't cc or kite bosses, so go melee
You need good armor and healing capabilities so that rounds classes down to the 3 plate wearers, warrior falls off pretty easily since selfhealing is weak, my money's on a deathknight(with a 2hander, blood/unholy talents similar to those runetap/master of ghouls PvP builds) though some would vouch for the paladin's dispells, DK simply is better due to better aoe, healing being based on HP percentage, lots of good cooldowns and better stamina and flat damage reduction percentages while not being railroaded into using a shield
For race, Blood elf racial is good but useless against the basic melee opponents, same with dwarf(though restorative pots do the job), orc/troll racials are solid but fall pretty far down because of bad uptime, Human and Tauren are good all-rounders while the other races contribute close to nothing.
tl;dr go with pvp build deathknight with rune tap glyphed

DK>Pally. Wouldn't recommend anyone else. DK has best tank damage and healing.

A Druid works ok also.
They can stealth through half the dungeon and got quite some good dmg/defensives going on.

Yes it doesn't match the amount of healing a Dk/Ret can do.
But the amount of avoidance kinda makes up for that.
