I feel the gat correction was way overdone. It's essentially a laser now, melting armor insanely fast.
Pre-patch was 10 piercing/10 shatter, 5 bullets/s, 60 rounds (85 dmg/s against armor)
Post hotfix is 7.5 piercing/10 shatter, 8.2 bullets/s, 82 rounds (108.65 dmg/s against armor)
It would take just about the whole clip on a vanilla gat to destroy the pyra armor, even with someone fixing the ship. The same holds true now, but takes a few seconds less.
Then if you use greased rounds, you could take that time down to about 9 seconds. Now if you used greased with the post hot fix gat, you can bring the time down to just under 7 seconds.
Here's a short video of it in action:
http://www.youtube.com/watch?v=XnOV3THPSacYou can see them nuke down a pyra (with the help of their ally) then a galleon (a lot less help from their ally) and finally another pyra (all by themselves) in less than 2 minutes. Be aware that this is a highly skilled team, using greased rounds on the gat and buffing their guns (bringing the dps up to 166.88 dmg/s; and the time to kill the hull while someone is repairing it to just around 5 seconds.)
The old dps felt too high, and the last patch felt a little low, but these new numbers feel a little too intense. If you start getting hit first, you have almost no chance to maneuver away or recover.
