Deathray needs nerf bad.

To me, it seems the stronger your feet, the stronger your enemies. I've done a couple runs with just projectile cannons and hardly any death rays. But this is a rougelike game...sometimes it'll be impossible and sometimes easy. In the cases where there are a great number of death rays, you hit and fade or use beacons to draw the ships out of the sector you're trying to go into. wait for your openings, strike fast, and bail.
