Vortex 'Black Hole' MTX visual area is too small

The visual area of effect using the MTX is smaller than without it. It makes the skill's area seem much much smaller than it actually is.

Took a collection of 4 shots spamming it and casting once. It was all done with 25% inc area in tree and 10% inc area through quality.

Think that's the actual size. The Normal Skill Effect has additional particle effects which make it in general harder to tell which is which.
