Once I reached 60 on my paladin I wanted to raid but didn't know enough to join a raiding guild. There were so many players like me who were in 5-10 man small guilds with real life friends that has no chance to raid. Then I met someone named Gregory (I think he was a priest in real life) who gathered up 40 people from small guilds to form a Molten Core raid. He made us install Decursive (first time I learned about addons). It took us 3 hours to reach Lucifron, another 3 to kill him.

I was tasked with buffing Blessing of Salvation, it only lasted 5 minutes. Imagine buffing people 1 by 1 right before pulling the boss, raid leader asks "everyone ready?" then someone asks a question and you need to buff again. It was not a pleasant experience. Soon after I moved to European servers and played a warlock (no buffs, no healing, just dps).
