The result is extensive rebalancing to suit the weapons as they were originally intended to work but didn’t for the longest time, which may or may not mean that you still like how the guns work. It’s also important to note that they have a small leadup; the beam ramps up from 10% to 100% damage over 0.8 seconds, then falls back down again quickly, so you’re best off firing in quick shots. There are other balance changes with the latest patch, of course, but it’s this reworking of beam weapons that’s going to mean the most for longtime players.
