The death vortex is especially odd... It has the CC graphic, plus an EC graphic that isn't a particle effect as far as I can tell. The EC-only graphic has a problem though, its getting the top and the bottom of the effect chopped off when it is at the largest point making it look like the effect is being viewed through a slit.
We had a rainbow moongate on GL that was kinda pretty, but you could barely even tell it was there in the EC. I'd rather see moongates in the EC look cool like the corrupted Honor gate...maybe with some particle effect "mist" coming of it.
