Any way to get the mission markers to not show on minimap?

As a solo player, or at least me anyway, i rely heavily on the mini map to find enemies.

Especially with the prevalence of splash damage obstructing vision. The freaking diamond can often take up the majority of the mini map.

Combine the giant diamond with the giant boss icon and trying to find the minion mobs becomes and exercise in frustration when you are leveling a character.
