I actually think root is a good guess as far as leveling goes because it is widely shared and a lot of people never use upgraded versions.

However, I think raiding has drastically different numbers. No one is casting root in ToV, however CHeal might be getting casted anywhere from 1 second to 5 seconds apart for all the major and minor encounters.

I also just wonder about later levels in general. A wizard may cast several nukes or tflux staff clicks per root, a paly several Yaulps or Flash of lights, etc...

Also of course as others have said the Canni casting is real.
