Why do people make such productions out of quitting the game? Is the intention to try to pull a Jerry Maguire and see how many people will walk out with you, right then?
I took a break from wow myself right before MoP (I've since come back) and when I left, there were no blog posts, no videos, no long, drawn-out posts explaining the reasons.. I just left.
People grow older their priorities change, and they move on. New people come along, with a different way of enjoying the game, and suddenly the older people are complaining and actually quit over the fact that things aren't the way they used to be. Guess what? If all of your old friends from 10 years ago all still played, everyone still had as much free time as they did 10 years ago, things might be the same.
Now that tank you raided with has 2 kids and is out playing with them instead of helping you rep grind. Now your old healer has a successful career and she has to get up before dawn, so can't stay up running 5-mans with you anymore. The new kid comes along, he plays wow, but also plays other things and wants to get in, get a quick LFR, or quick random 5-man, clean out his garrison's mine and get back to what they were doing.
Yes, the game is different, but it's not because of Blizzard or anything that Blizzard has done, it's because of the PEOPLE. So grizzled veterans have two choices. Leave in a huff... or maybe get to know the new kid that's young enough to be your kid shudder help him learn the game and master the stuff that you've enjoyed for so long. Meet new friends... if the people you used to hang out with aren't on to chat with anymore, find new friends! Keep pressing on and meeting new people until you find a new group that you want to hang out with and do things with.
Plan events! Just tonight I planned a guild run of 5-man achievements. We got 9 done tonight, it was great! People were online that are NEVER online on weekends, but because I actually took the time to plan an event, they showed up.
Am I alone here in really not wanting to read more "I'm quitting" posts or more posts about people whining how things weren't the same? MMOs are an evolving game. If nothing ever changed, and it was the exact same as it was 10 years ago, you would be SO bored. Embrace the new, enjoy the game for what it is! If you do decide to move on and cancel your subscription, fine, but keep it to yourself.
