Curse circle missing if instant cast

tittle as it says...

There is no visual on the curse circle range if curse is instant cast.

Usually I'm not looking at my character if it was cast or not, but on the mob

Also, since I'm running 2 curses that shares a similar display, I'm not sure if it was casted on mob or not, neither if the mobs on nearby range also got cursed.

Would be nice to have some visual display when cast time is instant
