Well I deleted my character when I felt I was too attached cause I felt I was starting to take things too personally.
Gotta say starting fresh does help a lot with that. Just delete/pause and move on to a new younger character on a different realm full of people you haven't played before.
I must agree the game has changed over the years. When I first started, the atmosphere was less serious(I blame SMA for this!) and people were more casual. They also did a lot of silly things. These days if you do something silly you get branded as a traitor or an idiot.
Either people have lost their sense of humor or the game got a lot more serious than before. Also, there are too many people who want to mess things up than try to do something together with others.
