way to optimize ork melee? Go slugga, take the electric choppa, take the 'ard armour. Make sure you take +2 stamina and take the +20 toughness. Learn to roll around and land a spring attack on them it will break them in half. now this does leave you with no grenade and health packs but its a good trade off imo. make sure you roll behind people to prevent incoming fire from hitting you.
