Same happened in maduolan, I remember when I joined Cow eaters in 2007 I was invited into a guild and was the only one online for like 2 weeks, with the exception of one guy who gave me some gold one day.
Then suddenly i get told there was another "more hardcore" guild on the server lol, was full of people. I remember I was pissed caus my hunter was level 50 and they told me they had too much hunters and if I wanted to raid with them I had to roll something else
Well years later, and after seeing a lot of drama around me, all I can say is that if some people wanna be hardcore(5-6 raiding nights a week) they better think about their own hide and join a Chinese guild. That's what most ended up doing back then.
But the current TCW is really the hottest expat guild I've ever seen since I started on the chinese servers. PVE, PVP, special events (kudos to malice for coming up with ideas and organizing those things), over 100 lv 85 and still counting.
