Why does root suck?

[commongood]

I'm gonna bandwagon this thread and ask a root-related question:

Does the level of the root spell influence the odds of having it break upon direct damage?

So if I have a mob rooted and I then cast a nuke. Will the chances of that nuke breaking my root increase if it's the lowest lvl Root compared to if it's, say, Paralyzing Earth? Or will both of those roots have an equal risk of breaking upon a nuke landing?
