It's not just totemic armor... also jaundiced bone (Kunark).
Mainly this:

But other than those armor sets there should be plenty of choice with Velious regarding armor.
Iksars make good shammies with the regen + AC bonus.
Disadvantage besides Totemic/Jaundiced bone is imo only the fact that they're being hated everywhere but Cabilis (not a huge impact). And the look... If you don't like lizards.
