-Just let Titans do Wing Chun hand movements, before they throw down a fist of Pani... Havoc/Punches or/and shield barriers.
-Warlocks doing (doctor strange) type of hand ritualistic movements for when they place rifts down, Throw Nova bombs and/or Well of Radiance.
-And Hunters do Ninjutsu Hand signs before they disappear with their class abilities and/or when they throw out a kuna..i... I mean knives.
Instead of an unnecessary and random third person animation replace that animation with something much more fluid and faster, such as these hand signs?
At least the cast time for class abilities would be faster without having to venture into a random third person animation.
