So I am currently using the plasma beams, but am getting sick of the spring sound, do you lose much by choosing to use disruptors or phasers at higher levels? It would seem with the new skill point cap that you can't afford to invest in multiple weapon types.
Phasers and disruptors are probably two of the better weapons, if not the best. The problem being that finding certain versions of them can become problematic as after a certain point you begin getting, almost exclusively, the later tier weapons as missions rewards. Odd, I know, but apparently the Federation becomes loathe to part with Federation Phasers after a certain point.
