I think a lot of people are discounting their own growth over time in pvp skill.
I've noticed this in my stints of coming back to disco over and over, for years.
People who start disco, even from another server, have a learning curve. Its actually quite a long learning curve to get to be near the top (and most people who join this server as great pilots are actually people who've made a new account...I've known more than a few)
While I'm not saying nomads didn't get a nerf, I am saying that, in 84 and 85, I fought nomads, and didn't have the experience of absolute fear of 1 on 1s...unless I was fighting, for example, Virus. After jumping out and in, I found the game much harder to fly in, and not just because I lost my skills, but because the community as a whole is progressing, learning tricks in meta and passing them around, and players get better.
Just a thought, but alongside the new balance, have you considered that the skill differential between the nomads (who have often been fairly experienced players, based on their demands for high rp skills) and all the rest?
