I want to express that you do not necessarily need a fully charged, and fully scoped E-Liter to One shot someone. With damage ups, and good accuracy, the decreased visibility is merely a fraction of what you're making it out to be. Now, yes, the fact it zooms in the way it does can be a hindrance however, if you're planning on maining or working towards making the Scoped version your main, you're going to have gear aiming towards capitalizing off that. And with enough damage up and practice, the decreased visibility is cut nearly in half.
