After all those years of gaming, I can only state one thing - when games became pure business, both for creators and players themselves, everything ended.You definitely know something's wrong, when a computer game becomes like a second job; at least, you should by then.
If it's not fun anymore - don't play it. If you're getting stressed out, instead enjoying it - stop playing it. If you feel like other people are taking away from your own enjoyment - leave them behind and find something else (propably better) to do. I had my share of bad experiences, caused by feeling "forced" to do things because X/Y/Z required it, rather than playing for my own personal enjoyment. It's also a direct indicator, developers have failed at designing the game and put other, less important aspects over fun and engaging player experience; worst of all, they're mostly unable to see such mistakes being done and repeated.
I quit mmorpg's and I'm not planning on going back. I'd advise you all to do the same - there's literally nothing those games have to offer nowadays, except for a massive timesink; time, you could use doing more constructive things, like reading books or visual novels . Trust me - once you stop giving a damn and let it go, life becomes so much better.
