That would be too strong. Yes, roll dodge is the main "defensive" mechanic stambuilds have in Cyro. But still it doesn't mean that feature need to be added, otherwise, as people said in the above, that would be really powerful.
Snare removal perhaps, but not immunity. You should have to slot an active skill for that.
That said, Double Take and Boundless Storm should grant root and snare removal and immunity imo.
