To date, the only MMO I've played that I think got PvP right was DAoC. RvR was fucking badass. Why? Because I could be in with 1000 other people and not have to sit in some bullshit queue. Granted lag was terrible and I don't think they ever really worked out class balance but even that wasn't terrible. The PvE stuff was not all that bad either.
Create another game like DAoC, fix the buff bot issue, figure out how to not put in some cap on PvP so anybody can just jump in, and have decent PvE content. I'll gladly pay you $15/month.--
