Had a look around and couldn't find anything on this post but apologies if it has been posted.
In dragonblight there is abit of land only accessable from Wintergrasp or with a flying mount which allows you to actually fish all the mats for Fish Feasts apart from the spices lol. (the co ordinates for this place are 26,47) you dont get queued for WG so u can spend as much time as you want there. only bad thing is if u die u cant get back to ur body which means you have to accept a res sickness =(
