Stygian Chain Hook and Rage

I was messing with Chain Hook and decided to grab the Stygian MTX for it since I thought it looked cool. When using it though, I noticed that the rage effect that's bound to the skill still gives a red aura over your character. This clashes very hard with the blue effects that the new chain hook gives. I think this should be changed to be a blue rage aura similar to how ignites and other effects get changed when using an MTX that changes the color of the skill. I feel like this was an oversight that could be addressed with little effort. Thoughts?
