LeBlanc and Karma snares

So i think it is very annoying that you arent able to dodge LB and Karma snares by going invoulnerable, not on the inicial hit but when the snare activates you can't dodge it with zed or ekko ult or fizz e etc. I think it is just very annoying and weird mechanic and i think you definately should be able to dodge those type of spells with invoulnerability.
