While I agree that people need to relax a little bit I can certainly understand why they are upset. I for one have been lucky as I have been on graveyard shifts and can play in the middle of the night and I don't have any problems getting online. That being said when I try to log on pretty much anytime after 9am PST all the way till about 10:00pm PST I can't....
I do have friends that play during the day time and for the most part they are stuck there spamming the 0 key trying to get in over and over for usually anywhere from 20 minutes to an hour before they get on.
I for one have a better idea then most as to what goes into setting up and maintaining a server on this magnitude as my field and profession has me in a data center every day at work. That being said I don't really believe that they couldn't have seen this coming. While it is possible that they could have received a lot more people then expected after launch due to people just picking the game up after release, the number of people that pre-ordered was probably evident in the weeks leading up to the pre-launch access event. I signed up for and got into the last beta phase only to be met with full server messages the entire time and I was never able to actually get into the game. I am not the type of person that is content to just sit there for an hour spamming the login screen trying over and over and over and over until finally the game gives in and lets you through, if I can't get in within the first few minutes I just move onto another game. While I am not sitting here losing my mind and screaming bloody murder it is a little aggravating when I can not access a game that I did have to buy albeit I am getting the first 30 days on the house.
I am a strong supporter of an AFK checker, and for the life of me can't figure out why it hasn't been implemented yet but I can only hope it is coming. While I don't think it will fix the problem with a snap of the fingers it is pretty hard to argue that it won't help. I just logged off after playing for a few hours and it did not matter where I went , there are a TON of people just afk in the sanctuaries that have not moved for the entire time I was on. I would run past and sure enough the same people are just chillin......I for one don't understand it. If I have to go to the bathroom ok I won't log out...if I am going to bed, why the hell would I stay logged in ?
I was around for the WoW launch and the SWTOR launch and lets be fair...they didn't fair any better, and in some cases faired a lot worse, WoW was a mess when it launched. SWTOR had a similar overcrowsing issue but when the caved in and added a bunch of new servers they faced a new problem...the game didn't do as well as they had hoped and when people left they were left with a bunch of low pop servers with no one using them which just ends up in more people complaining because their server is dead.
My advise to everyone who is really upset is to give it some time....aside from the people who are missing their free 30 days for whatever reason or another , you have 30 days to play for free to see if it gets any better. If it does not get any better well then that sucks and at that point I would probably be seeking a refund myself , but I would not be surprised to see at least some of the issues be alleviated somewhat and have the play experience be improved when logins decrease a bit.
