It comes down to a balance thing honestly. Certain champions have it because without it, they wouldn't be able to survive team fights, Fizz and Vlad, Zed instead get his burst and flash every 20 seconds. Also giving him untargetability, would make him a little too strong perhaps, but that isn't for me to say, Riot will decide that if they nerf/buff him.
