yes, I am a fan of flanking rules. So you can position yourselves on opposite sides to gain advantage on attacks. Imposing disadvantage is usually harder, though some spells and abilities do that.<br/><br/>you can take the Dodge action, so until your next turn begins all attacks made against you are at disadvantage, that eats your action unless you have an ability that stats you can do it as a bonus action like Monks Patient Defense.
