shocking grasps being a melee attack isn't much of a disadvantage. The mage doesn't want to be in melee, but you can move, use the spell and move away in the same turn, and without any mechanic that allows the frontline combatants to lock enemies in place or discourage them from moving or attacking elsewhere, it's almost impossible to stay away from any enemy that wants to attack you in melee. The only way is to remain out of their range.
