Brand's New VFX
While they're nifty, I wouldn't exactly say they're visually clear. The W (the spot cast) could use a circle around it similar to Cho'Gath's Rupture, the particle is light and a little too hard to see around the edges. The ult is also a little too light because it's amorphous, so it looks as though it could be going any which way. Maybe it could be darkened just a bit.
Just my two cents, as always, you have more data to work with and I trust you will come to the best conclusion. :)
