So, I returned to the game, and want to level a undead character with the following aspects:
1.) Good solo'ing capabilities of old dungeons/instances
2.) Good daily grinding capabilities
3.) Enough options to join a raiding guild if wanted (so no unwanted class )
4.) Either Hunter, Rogue or Priest
Why this topic? Because I only have the time atm to level 1 char, and like all 3 equally
Could I suggest creating a Monk if you haven't already? It is a fun class to play; agile, has a lot of utilities/perks and powerful. This applies to most if not all three Monk specializations. Not to mention it would satisfy almost all points of your requirements
