To be fair, Mark/Dash is pretty fun, unlike Clarity, it's just that the spell was mainly there to try to "fix" champions without the reach to do well in ARAM, who, as you mentioned, are dysfunctional without it. The issue is that all champions who can't poke tend to suffer in ARAM, so the game mode probably needs more effects on its aura to make engage champions work. Generally, fixing a dysfunctional game component by adding an "optional" extra effect doesn't work at all, and makes the issue more complicated to properly solve later on.
