I actually made a post like this in Gameplay Feedback as well, more centered on specifically Zealot though.
I’d personally be all for it, gives back some variety to the tree’s and makes it so there isn’t just ‘this one path’ for every build. I like it on Ogryn too because their CDR node is located right after the middle ‘25 toughness node’, which isn’t really a tax as you’re taking that on every build anyway, so it’s just like ‘ok, you can basically always have it if you want it’. So I’d like to see this, think it would be a nice way to allow some CDR nodes to still be potent percentages while not just breaking every CA at large (like taunt having to choose between damage and CDR).
