I was playing with the Gauss Cannon, but was disappointed by how inaccurate it is. I found two changes which make it into a sniper
. They may be a bit much but if you want to have fun:
1) Change the chargeup from 1 to 0 and the cooldown from 1 to 2. The gun traverses even more slowly while charging so even if was accurate when it first starts firing it won't be a second later.
2) Change the speed from 1200 to 1500.
In testing with a normal crew with ITU on a capital, this let the Gauss cannon hit frigates about 40% of the time at 1600 range, 20% at 1800. Its probs a bit much, but so much fun.
