Question...
Answer….. no. For pve the best noticeable impact any profession can bring is high dps/burst. Now for wvw zerg setting it can be a different story.
Heidia- The elementalist is the #1 most OP profession in this game since beta!
With a little bit of coordination it can however. Any profession with a blast finisher or two can use the water field to blast out good healing, and in the close fights of dungeons, a Thief spamming Cluster Bomb or a Guardian using Mighty Blow can do quite a bit.
However, for fractals, especially higher levels, you’ll probably want to run either D/F or S/F, the Air and Earth skills on Focus are invaluable, and complement well with a Mesmer or Guardians blocks and reflects.
