Which class would solo PvE better?

What class would you say would solo PvE content better, both old content and new? A Death Knight, Prot Warrior, Prot Paladin, a Feral Druid or a Hunter?

Which would be better for attempting to solo current (Cataclysm) content? Such as trying to solo nm instances? Group quests?

What about old content - such as Northrend nm & heroic instances? Northrend Raids? BC Raids?

They all seem to have the potential for it, and some classes are better known for it (DK, Paladin & Hunter). They all have ways of healing themselves, except the hunter - however hunter can use pet as damage sponge. They all have ways to mitigate/reduce damage.

DK is tops. blood heals a ton, so it dominates old content. then you can bounce frost to howling blast range kite stuff (eg: solo firelands trash farming).


feral is next, and has it's own set of advantages.


the other 2 aren't really comparable.
DK is pretty good, but hunter is the only solo class that isn't. You can have a tank/healer/dps combo set up with a hunter that you can't with anything else. Anything where you need to have multiple targets, hunter's pretty awesome.

However, I will agree that DK is probably still the best. Army is pretty lulz, on top of the standard reasons.
Darhan - I'm not sure what your saying. Hunter is not good at solo'ing? or is good because they can switch pets for different things?

So it seems so far consensus is that DK is the best, followed by either Druid or Paladin? With possible hunter next or before them with warrior coming last?

Thanx for the responses so far :)
