Well they wanted to have mages step in to be the elemental experts in dealing with the primalists for some reason.
Totally agree.
Shamans are a cleansing water class. Lightning makes thematic sense when you consider how they splash water on people then electrocute.
Cleanse and purge.
Also they don’t answer to the elements like, “thanks elemental king. I’ll follow your commands”.
They’re more like, “what’s up elements? What’s the weather gonna be like today?”
