Don't listen to them they're lying, this is what you must do with a melee LI:
Just kidding :P
But really, equipping a melee LI is a very useful, in particular the legacies 'Needful Haste Duration' and 'Critical Magnitude in Precision Stance' are very useful and should be slotted on almost any melee LI regardless of build. Depending on relic choices and slotting 1 or 2 stat legacies (agility and either vit or fate are popular choices) will result in a greater stat benefit than pretty much any one handed weapon you will come across, in addition to the skill modifiers from legacies.
