A stun totem, a slow totem, a tremor totem, a skyfury totem, a counterstrike totem.
So yeah, without totems, enhance shamans would be literally useless. Calling them a “Totemic Warrior” completely makes sense considering a majority of their power comes from totems.
In addition to there not being that many totems, the whole idea of totems being a ‘class’ of their own was scrapped in Legion.
The whole “1 totem per element”-thing and there being several in every element to choose from was, for me, very iconic to shaman.
Now they’re just normal spells with normal cooldowns and whatever restrictions/freedoms apply to your regular spell.
No unique mechanic attached to them.
