What a torp shm / enc can kill/camp that cleric / enc cannot?

[Rygar]

I would think with rune + torpor+ spot heals a shaman could tank a slowed Gwurm for a very short bit. You need to get lucky with the charm breaks and have additional charm pets at the ready.

I guess the point is I think it is possible with shaman and chanter, just don't think it is possible with cleric and chanter (think cleric would get oom too fast even with chain charming pets).

This all is assuming straight up no tricks like strings or bladestopper or soulfires or 8 bags of wort pots or something ridiculous like that.
