Honestly, I think the only thing here that is positive is an attempt to force people to roleplay....and I do believe that people need to roleplay in every character to have any right to be on the server.
What I dislike, and this seems backwards, is the attempt to change the rules by changing the game...I rather like the environment the way it is, and as jinx said, there's not too much there. the Traderoutes need some balance, yes. There are packs of capwhores roving about, so I've been told. Haven't seen any for ages, but maybe thats because I expect liberty to be horrible, and avoid it. I don't think much of this would help the server in general, but giving guard pilots train cds would make sense...but my train gets stopped 3 times out of 7 anyway, so I'm not sure of the point.
All in all, you've had a bad time with packs roving around, doing things inside the rules but outside of a sense of fairplay, with little or no RP, and I'm sorry about that, but I don't think many things need a nerf, just a few of the unbalanced ships.
