How strong a Shaman that never gets Torpor?

[Vanessa]

I've read that in Kunark, Shamans are like the best soloer / farmers. I was wondering, is that true because of Torpor, or other reasons?

I will likely never get Torpor, even if I did, I would probably sell it for like 100k-500k plat and use that $$ to try out other characters haha.

Considering that... how strong is a Shaman for solo leveling and solo farming, if they never plan to get Torpor? In that situation, would it just be better play a Druid or Necromancer?
