Not gonna happen. I'm fine with snares ignoring it, not roots. A root is the epitome of a CC.
Play a ranged class and don't use roots when someone is white-barred, and see how fun it is.
Snares/roots are part of the kiting/anti-kiting game mechanic. The devs aren't going to change this w/o completely rebalancing all classe, and that's not going to happen.
