You guys are probably already working on changes to Shaman, but here’s a suggestion for a node: Increase or Flat Totem damage converted to melee or spell damage for your character.
That way, you can focus on spec-ing into totem increase/flat damage and also buff your character. This could be a unique way to build up your character as a shaman and create some additional builds that are not only focused on Totems.
I know that there are idols that give you increases based on number of totems, and also passives that do that, but I think this idea would be a great addition as well.
