Between Warlock and Bear Druid.


I would like to know that which class can solo Dungeons & Raids greater than another one?


and which class can solo easier than another one?


and which class can solo more Boss than another one?


Any info/advice is appreciated.

Class doesn't matter much for soloing most old content. Bears or Blood DKs for heals are good. Please, no need to post this more than once.
