Just suggesting a very minor edit to Blind Sage, why not swap the Fire damage node with the skill node, and make all 3 elemental modifiers branch off of that?
This just makes the devotion a bit more customizable for what you specificly want (Lets face it, it has 180% damage to all elements, a good chunk of stat power). This just means that instead of being forced to get the Fire damage node to get the Blind Sage proc itself, you can either…
A. Chose to not get a modifier to any of the core elemental bonuses, saving that single point for something else.
B. Chose to get a modifier to the specific element you are focusing on, enabling you to get the +100% to Lightning or Cold instead of Fire, in the case of the current way Blind Sage is set up based on what you want to get.
Its very minor overall, and if you don’t change anything but the node placement you won’t affect any builds that go all the way for Elemental Seeker at all, but will boost builds that only want a single one of the damage types as well as the Seeker Proc, or at least allow them to save the devotion point for something else.
