Dev Suggestion: Make Dark Arts attacks have new animations (think 4.0 MCH)

Pretty simple request.

In 4.0 with the new Heat system, MCH gets changes in animations that look awesome when performing their three step shot combo. I would like to see Dark Arts have the same effect on Syphon Strike, Souleater, and Power Slash. I think the oGCD abilities' animations are fine as-is (especially Bloodspiller which looks amazing) but yeah, it'd be really cool since I wanted it in 3.0 and apparently it's possible.
