The slash effect and the fact it uses the melee swing animation are relics from when it was a melee ability on Beta. I am honestly surprised they didn't update it to a cast spell before it went live.
Also, it should be mauve.
I believe that now with the new questline which has more or less to do with chaos (illidan artifact?) we will get a new animation during the patch, cause it will directly affect the demonology feeling. I think its a high priority thing to look for, otherwise the cripples the Meta sensation.
why can't i have instant cast hadoukens like ryu in street fighter ex3, but purple or green

Another animation suggestion:
Give Shadowburn an actual animation like a brief immolation of purple fire similar to how Lilian Voss does it or some Twilight Dragons.
Void Ray looks atrocious. Rather they change that first. ToC at least has a smooth feel even tho you look like a big demon trying to catch butterflies.
I think that they are trying to "define" the Chaos school of magic better in the upcoming questline. Then we may see more similar spells and ToC gets a unique animation. Keep in mind that Chaos damage is the combination of every element in the game including physical as well. Impressive.
