ARAM: Snowballs Should Just Be For Throwing
I believe Mark & Dash (the snowball spell) should have a different purpose in ARAM. Rather than how it is used/works right now, I believe it should be used to only deal damage; and not to mark (and grant vision to the marked enemy) for a period of time, and within that time have the ability to dash to the opponent. This is because high DPS/burst damage champions can use this spell as a gap closer. I believe this spell should be used for champions (or team comps) who are melee and may have trouble dealing with poke. Yes, obviously ranged champions can still take this spell, but they won't be able to 'abuse' the Lee Sin mechanics (because there won't be none).
This is my opinion.
