It's really easy to look at the past, mention all the good things in your memory, but completely disregard the overwhelming amount of bad things that were there at the same time. Have things really changed that much? They didn't. The community is fundamentally the same it was 8 years ago. People may not like this word, but saying otherwise is nothing more than nostalgia. I am not with saying these good moments and experiences didn't happen or weren't as good as you say, I am no one to say that. But it's foolish to omit the bad to paint the past as something better than it actually was.
We all have fond memories of the past, not just in WoW. We all remember all the awesome experiences and events we went through, all the awesome people you met along the way. But that doesn't mean, in any way, that the past is is better than now, because for every awesome moment, there was at least a bad one, and a few moments of nothing.
