Is it just me, or is the phase beam a very, very weak weapon? Virtually every other medium energy weapon is a better use of OP. If you want raw DPS, it's a better idea to equip heavy/mining blasters. If you want sustained fire, invest in pulse lasers. If you want to take down a shield, use graviton beams. Right now pulse lasers do everything the phase beam does, but better. The higher flux cost is offset by the fact that pulse lasers do far more DPS and have low OP costs, letting you equip more vents to offset the flux.
Aside from looking cool, what does the phase beam do well?
Anyhow the point of this post is that I think this gun needs to be reworked. It's really cool looking, but it currently has no role (I know it used to be a weapon that killed phase ships, but those mechanics aren't used anymore).
I personally believe that energy weapons tend to be a little weak in the anti-armor department (whereas ballistic weapons do all types of damage well). I think it would make this gun relevant again if the phase beam did high explosive damage instead of energy. Plus I'd feel like I was shooting one of the capital ship lasers from Freespace or something, just tear a ship apart if their shields went down. The phase beam would finally have some "oomph" to it.
