When I was at my peak I was somewhere in my early twenties. I never cared much for dueling but I did and still do enjoy mixed groupfights a lot.
The time when I was good is long past me now and ever since the raid gamma every day days I notice that I care less. There's a small group of people that is so incredibly good at PvP that theres basically no point in trying for a rusty old player like me.
Things have changed a lot, and now that it becomes dangerous to deal with an ace by overwhelming numbers, and there really isn't much to enjoy about being someone else's NPC, I opt out of PvP more often.
The real strength of this game, in my opinion is the roleplay, and in the rare case that a fight is really equal, its amazing!
It must suck to be an ace nowadays, all that time spent on honing a skill but nearly every opponent that isn't on your tier (the vast majority of the community,) feels like interacting with you outside of conn is a waste of their time.
I really don't know a solution for that, all I know is that I'm happy being average, and I don't think its healthy to want to be the very best pvper in this game. That energy seems to be better spent elsewhere.
The game is more enjoyable for me when I don't feel like I need to prove myself. Not just for me, but the people I interact with as well.
