I think the mod elemental difference adds more depth because it makes you consider different elemental types for different things. The elemental type coupled with limited energy (10 max each) makes use make difficult trade offs. If all mods were available on every element type we will just end up putting the same (go to) mods on everything. The ones that are universal seem fair. It’ll (in my opinion) homogenize build crafting. Make it so we have that one optimal build in the game.
