It's sad that the bugs (clipping on doodads, etc.) are still there even from when I played on beta. Although the pvp is fun, it's something that's just fun when a lot of people are doing it. Since the game died down, they had to consolidate a ton of servers into 4 servers last I checked. It's probably less now.
First tier may be nice, but that's because it's free to play during that tier. Tiers 2-3 are the most boring because they hardly have anyone going through them, and it just makes for a dull experience. Tier 4 (last tier) has more people doing it, and I guess they improved the city raids.
The game had potential, but they released it way too buggy and the queue times on the high pop servers were ridiculous, especially when you got disconnected 40 minutes into them. That caused people to up and quit, thus crippling the entire PvP aspect of the game due to lack of players and obvious bugs that affected the experience of game play.
I believe they used the same engine as one of their older games as well, which also was a huge mistake.
But really, the way open RvR works in that game was amazing if there were enough people there, and that's something pretty unique to that game which made it fun. Too bad the other problems overshadowed it, and some of those problems are still there today.
