For me, the energy blaster kills most things at long range. Those which cannot will be killed by the mini gun.
For me, the "gravity" line of weapons, starting with the lance, need an upgrade. Either the "lance" needs 2 beams or more firepower or the base "lance" needs more damage, because right now it has the range of a shotgun with the power of a BB gun. It barely overpowers the previous "go-to" weapons of blaster or minigun when they have a resistance, but lacks any range.
One suggestion:
The "lance" turns into a "laser". It can strike two separate targets per burst. Thus the weapon accomplishes its goal of striking multiple targets without the edge cases of abuse.
