Honestly, there's not much need to focus on the PvP aspect. It is very much a PvP game, and if you feel motivated to become better, participate in more fights and you will.
But I feel most people's priorities aren't to be the best PvPer - it's a roleplay server where most of the gameplay lies in doing communal activities, speaking with others, trading, interacting. PvP is inevitably a part of interaction and roleplay, but not the "main" aspect. This is especially more relevant nowadays as most fights are group fights, where coordination beats raw skill.
I used to be one of the better ones when it came to flying bombers, but as time went on and I fell off from not playing, I've found zen in just doing okay, and focusing my effort elsewhere. I'm far from an ace nowadays, and not really interested at all in getting back to that point. If I get to fly with friends and have fun, I'll opt to do that instead of sweating in Connecticut trying to chase the mythical ace skills and feel bad when I don't beat aces anyway.
In other words, I play after work to have fun, and stressing over trying to become better and my performance isn't fun. If I get to participate in fights, I just do it to have fun and try something wonky or funny. As Sombs said, plenty in the game to focus on other than sweating in PvP enough to "get good".
