Well, since someone so kindly pointed out I was the topic of discussion.

While Delanan was undoubtedly a powerful character, I never sat in wall of thorns. Other shamans did, but I was too impatient to sit in a wall and hope someone came by. I would highly doubt if WoT was featured in 1/3rd of my PKs. That's like (old) rot - lame-o.

Outside a wall of thorns, a Sylvan shaman was not that unspeakably deathful. Since 75% of our fights were against Master, it mostly involved us raiding them, where insects would fail indoors like 75% of the time. Shaman isn't even a terribly good class for mage fighting - I was actually pretty useless against (smart) invokers and such, so a lot of the time my primary function actually was to lead, tell people what to do, and then spam dispel.

It was a powerful character, but mostly due to its survivability. For kill power I'd take a necro any day.
