I've been playing since open beta and thu the early start. The PVP has been so much fun I've hardly done any questing.
Here's hoping it stays this much fun to the end!
Someone, or group of someone's, put a lot of work into keeping PVP fun (competitive) for everyone. I didn't realize this until I started using tier 2 quests but players past a certain level will not be fighting against lower level players.
You can join an open RvR and get around this, but the Core servers do a marvelous job of letting players fight against each other without the A holes that ruined AoC running rampant.
And in combat you get your level bumped up so that you can at least have a fighting chance. The level 1 guys get a bump so they can fight against higher level players and still enjoy it. And at a certain point you get bumped into another tier and you can't go back... (or can you? maybe your level is dropped to reflect the other players?)
All in all the PvP quality is exceptional in this game. Really deserves a lot of mentioning.
