Shaman weapons

[Mrpink64]

Hey guys . So I’m restarting my 39 shaman. Gearing him up now (iksar)
I’m torn between what weapons to use.
Should I go fungi staff or rune etched icewurm fang to face tank?

Will be 80% solo rest would be a duo with my brother who’s a mage.

Is a fungi staff worth it? Is it boring to play with? Also if I use a fungi staff does that mean I’ll only root rot from then on?

I already have a fungi and decent haste item.
Haven’t played shaman this far so not sure what way to go
