1. The crossroads
First time i went to crossroads was with 2 irl friends of mine at the start of wotlk, i loved that little town. I did all the quests there because i loved the barrens so much.
2. My first self made dungeon group
Back then you didn't have LFG so i found my own group using a channel we had. I still remember my first group doing the scarlet monestary, they became good friends of mine, i still miss them sometimes because we had so much fun doing dungeons together and had alot of funny and interesting convo's. I lost contact with them when i changed server.
3. My ravenlord
Today you see ravenlords everywhere, everyone and their moms have it but back then only druids could make it spawn (i still have that stone) and you needed a druid to make anzu come. That being said they were really rare back then they also had a drop rate of 0.4% and i did anzu every day. That day i killed it and thought "meh probably another gem" but omg "reins of the ravenlord" i stared at my screen for 5 minutes, it was my first rare mount ever. I kept getting wispers "whoa where did you get that mount" "sweet mount dude" etc etc.
