I like the Wrath animation, but the color just ain't right. Don't care so much about it as a caster, though, but more as the one possibly being on the receiving end. It's gonna take a lot of time getting used to it and being able to identify the person nuking you as a druid like you would do now.
Not too worried, though. Not only would it take little effort for them to recolor the spell, but there is also a chance that it'll all make sense again in 5.x.
Don't use Hurricane often enough to even care.
