In my opinion this is a very critical part to making mages exciting.
Not only do the casting animation of the hands/weapons need to be redone, but I feel the spells themselves need to be redone. A blob of red isn't fire. A blob of bubbles isn't water.
Also spell trails from the caster to the target should be implemented on some spells, also it would be nice to see some type of spells have CONSTANT effects. By that i mean, each time dia ticks for damage it could sparkle or emit some type of light.
