Yeah I noticed the majority of hate I got was 1-30, then 30-60 was still pretty bad. Now, I ran 60-70 while BC was still out, and in general I got little to no hate, most people were like "awesome!".

However, WotLK brought back all the kiddies and going from 70-80 I got a ton of hate. Now at 80 I get almost no hate again.
