I still remember when I first played waaaay back in Vanilla, the game seemed huge and left me with the feeling of being part of a community in a giant world. Loot was desirable and fairly unique, and pvp was less of a rush fest.
It could be my rose tinted glasses, but when I came back to Cata it all felt hollow, stats have got out of control, gear is so easy to get, the community-ness of servers has died, (Pug and cross realm raids anyone?).
I dunno, it all seems to have left me missing the past and not enjoying the present. Cata's extreme hand holding put me off for life really.
