I unsubbed a few days ago for a variety of reasons, including the lack of active players on the server.
Bioware/EA have shown they are not able to handle a massively multiplayer online game. They either lack the resources to do it right, or worse, lack the technical ability to. I stayed with the game from beta until now and it still is plagued with more bugs and minor annoyances than any game I've ever played. It also is terrible on performance - lag spikes, disconnects, and frame rate issues when there is more than like 10 people in the same area. I played the GW2 beta last weekend and was amazed how smoothly it ran all around. I remember towards the end of the SWTOR Beta saying "Are they seriously going to release this game in 2 weeks? This game is definitely not ready". Lo and behold, they decided to release it. Arenanet has the right idea, they've delayed the launch of GW2 for some time, and still have not set a release date other than "when it is READY". And hell from my experience with the beta, it's much less bugfree than SWTOR ever has been or will be.
Level 50 content is underwhelming all around. Some of the flashpoint encounters are the best parts of the end-game, but GOOD LUCK getting those groups together. Your guild won't want to run it because everyone's already decked out in full columi and rakata from the easy raids. The raids are WAYYYY too easy and some of the encounters are just a waste of time. Like seriously, who thought the "loot council" in EV was a good idea? Or Foreman Crusher in KP? The funny thing is the only difficult fights were the ones that were difficult due to the bugs that Bioware failed to address for months and months. Fighting SOA on HM used to be "difficult" because of how buggy it was. Once the bugs were patched, the mechanics to the fight are really simple and you realize you were just fighting bugs the whole time!
And about the flashpoints... they actually were some of the most fun content at level 50. But not having a group finder and only being able to group with people on your own server made this a serious pain to get together. People say they would want a group finder to be same server because of WoW cross-server community issues. This game will not have a community anymore if they do not at the very least MERGE THE DAMN SERVERS! GW2 Beta even allows free transfers to other servers! IN BETA!!! Oh, and give some options for PvE queuing. Why let there be PvP queues but no PvE queues? It's the biggest reason a lot of people don't even bother with PvE - it's so much easier to just queue for PvP.
PvP is okay, but nothing to keep me subscribing.
I have no faith in Bioware/EA to do things right in this game anymore. I really wanted this to be an MMO game I'd want to keep playing, but it really has just become a more interesting universe than WoW, but with worse everything else. I quit WoW over a year ago and won't be returning to that either.
As to what someone said: what game will I play to "replace" this? I won't be playing any more grinding for gear MMOs that's for sure. Now I spend more of my free time playing guitar, watching movies/episodes, playing SF4, SC2, working out, researching things I'm interested in, etc.
