I refuse to vote, because i pick the weapon most suited to the mission, if its usually close combat, like in tunnels etc, then i pick the shotgun, if its in a large outdoor area, i choose Uzi.
shotty even know even with the tier 2 weapons i still mostly use the 2x pistals and olny wip out the shotty out to quickly clear an area or if a special or hoard are coming for me.
