Truely a matter of opinion, but of course the mortar scores high for good damage; but it's hardly utilized in the many ways it can be used besides laming the enemy spawn point. "Mortar Melee" is when the mortar is used in several tactical manuvers involving close range, such as hitting someone directly with a mortar when you are adjacent to them. More common, would be to run to a box or any large object, and use the mortar while facing it, creating an explosion around you. Good for anti-melee weapons, but not so good if you are being attacked from afar, so that's why it is able to shoot further off.
