Yup, the lance is improved by phaser relays.
Gonna have to start stocking up on Phaser weapons to switch to for the Dreadnought Cruiser then. My Assault or Advanced Heavy Retrofit can get all those Polaron weapons.
Does anyone know of how to get over the ground attack glitch, where you're unable to inflict any damage yourself (turrets still seem to work), without leaving the map? Had it come up in Cure STF and didn't want to incur the leave penalty.
