Dani are you alive? haha.
On-topic; I play shadow priest, feral druid and protection warrior and I just want to say that these classes are not bad at all, in fact they are really fun to play. However, in order to do good playing one of these you need to know and understand your class/spec, and you need to have it correctly setup with the right stat priorities/reforges and whatnot.
I see so many spriests and feral druids with completely wrong reforges and the rotation of a 12 year old. I also see protection warriors who has gear but has no idea what CTC cap is. Then you have that warrior who thinks he knows what CTC is and he is over capped like crazy, missing out on other important stats such as stamina.
I'm not gonna say that there are no bugs with these specs, but they are not bad. People just have no idea how to play them and work around certain stuff. This is a private server, remember that.
