I had a 40 within 15 days of release or so, and have 2-3 20ish, bunch of 12ish. I resubbed with wife since she likes to play. I could take or leave the game honestly. But it is a good game, I am just a bit burnt on mmo games.
The problems that I see directly game related:
1) Maps aren't very good at telling people how to get around because they either hide destinations, or the rvr flow chart indicates going one way and unless you have a quest that points you to the next area perfectly, you spend a long time puttering around looking for where the zone line is. Some of the zones are 3D mazes and can get a bit tedious to traverse. It's pretty hard on new people for the first time.
2) I have been waiting several weeks for people to get to 40 and do stuff. There are enough now to get the feeling of how it will be for another month or so. Pretty much Qing up the chase the boat part scenario. I really don't like that scenario and it's about the only thing I find people playing so I am playing alts. Hopefully they can add some of the other scenarios people want to play at 40, and when enough of the server is all in 1 tier (tier 4) serious RVR will start. So until then I pretty much play alts.
3) Itemization and PVP. I am playing my Ironbreaker through pvping for the most part. I find myself having to break away from PVP advancement system to get gear outside of it (PQ, AH, and quests). They are redoing items to some extent, so this should be a short term issue.
4) Running around large maps after death over and over. How many times have we in games, died, respawned, and then run forever someplace to fight, then die again, repeat... Maybe it's my age, but I don't like to run everywhere anymore. Leveling up by quests is bad enough but atleast you spread traveling between hubs. I would like to see them address large playfield RVR with spawns to keep running between death and fight a minimum. Thinking ahead on this because some of the tier 4 zones are vast, spread out, and maze-like.
Other than that I think they are doing fine. Asthetics is another issue. Population balance ties in to that and RVR rewards. But if you like pvp in bursts via scenarios, the game plays better than it did at the start, so it's progressing.
