Can snares/roots be changed to be more effective?

Back in Patch 4.1 Malzahars ultimate was changed to stop dashes and charges. I feel that this change should be applied to snares and roots as well. After playing Lissandra for a while I noticed that even if I rooted someone it didn't matter because it doesn't stop them from getting to me anyway. With it already having a shorter range than most of the games gapclosers it does feel bad I when root someone only for them to keep coming at me anyway. At that point the skill may as well have been do damage to that champion and slightly stop them from moving after they have already gotten to you since they were still moving for part of the duration.

I don't play anyone else with a root so I am assuming they all have this flaw.

I feel this would be a good change since roots are supposed to stop champions from moving. I would say to do this for stuns as well but there are a lot more of them and it already prevents you from attacking period. Still it would be a nice change IMO
