Which class can participate in a PvP raid, join a pre-made bg group, and then quieus directly afterwards as either healer or tank or dps in a undaunted dungeon, then runs solo in Cyro, and then casually finishes the day in the Maelstrom Arena, all that without changing CP or skill morphs?
Of course it is the StamWarden.
Warden by far. Designed from the ground up as a stamina class, even has a stamina heal. Only missing an execute.
Nightblade, of the original four, NB had the best, most complete stamina kit, and did not feel cobbled together like the other three. For example NB is not dependent on weapons lines to fill out its kit.
Necro is third place.
