Sawblade Blade Vortex

So I just picked it, and I'm kind of unhappy about how it interact with constant refreshing.

Animation is really cool, but when you constantly refresh it, the rotating blade will stop and get back to a random point every 1/2s instead of just keep circling.

Could you fix that so it just keep circling all the time ?

Will I tested that, I was supposed to have a 23 unit radius BV, 7,25s duration and enought cast rate (5/s) to make it up to 10 blades all the time.

Edit : I think the animation scall on the end of a old blade instead of scalling on the current total blades, may be that's why.
