Scholmance or Stratholme with 14 of my closest friends.
First proper raid was MC I did UBRS in 10 man but I dnt really count that tbh!! Loved the vanilla days..
My First raid ever?
My first raid ever was in Everquest 1 Original no expansion had a 70 person raid against Lord Nagafen. This was before Raid frames or that fancy stuff, most buffs were single target, 5 people per group, no raid chat. The Raid leader told me ( A Bard ) to stand directly under the dragon, i was scared shitless. We did win and I won a new set of drums, it was Glorious!
In wow my first raid was AQ20 and i hated that zone with a passion.
karazhan 10 man, was amazing
Always going to remember seeing "Welcome to The Molten Core, this raid is scheduled to..." and staring at two giants the size of a house and being like oh wait what this is huge.
Blackwing Descent, wiped all night on Magmaw and finally got him when someone logged on a hunter.
I think VoA
Karazhan, we downed 2 bosses and I got my first epic ever - cloth bracers for a healing druid from Maiden if i'm not mistaking ^^ was a glorious night for the newb ^^
First lockout raid was MC before BWL came out.
Few moments in WoW are more epic than a Guilds first Rag kill.
The hammer falling is pure magic.
UBRS when key was still needed!
When your enemies meet death , it is my face that shall greet them.
MC if we're talking a real major raid. LBRS or Scholo otherwise
MC, or for smaller raids: LBRS, Scholo, Baron Rivendare and UBRS
