"And why does his E+Q combo gets him out of Roots? I am not complaining, because I jungle with him constantly, just asking if it is right. I don't think Ahri can Ult out from Ryze's snare. "

Because normally any abilities that entail movement are disabled during roots but Dragon Strike isn't actually a movement ability, it just becomes one if you hit your flag... so the ability is still usable when rooted and presumably it was decided at some point that it was too fiddly to code it so that E+Q didn't work when rooted, but root disabling Jarvan's Q would make it too effective on him.

Also, I like things that don't proc special effects still playing the SFX, because otherwise attacking a turret with Jax would be nowhere near as satisfying!
