There are lots of PvE players that have a serious server pride without even doing much WvW and lets not forget the threads where servers and guilds were racing to kill Teq or 3-headed Wurm as first.
Server pride? When Anet introduces free transfers or a new season people hop from server to server like the world select menu is a bouncy castle.
Everytime Free transfers are introduced a lot of AP whores migrate to get the best rewards and Guilds change locations to get more competition on prove themselves, but at the same time a bunch of other people also stay trough thick and thin while their server dies. Server pride is a thing either you like it or not.
The only reason why I’m not hating the Megaserver idea is cause I know that the low populated servers have it really hard, while I had the best of both worlds for the longest time, but it doesn’t mean things are not gonna change on all fronts.
