As mentioned before, one of the many problem with EQ was that the penalty for failure was so harsh (and I don't mean losing corpses, that was the stuff of legend, but simply the lost time) that it was very difficult to find people motivated in doing anything other than the most secure grindy stuff. The rare spawn/rare drop system also encouraged people to stay at 'camps'. At the other end of the spectrum, you had lethal chaos. The train, the boss pulled on an unprepared raid, etc. So 99.9% of the time was spent waiting, travelling, grinding stuff or getting wiped. The remaining 0.1% (and I am being generous) are my fond memories.
Unusual group compositions (bard monk monk rogue in Sebilis' kitchen using AoE fear, group haste and single target snare!), dungeon crawling (Kaesora! Charasis aka The Howling Stones!), barely controlled fights (Hands room in Karnor with a greek guy who was 5 boxing that turned into an almost endless battle with the repops! Killing a mega train in PoFear with our chanter Crowde throwing the whole book at the sea of mobs! Intentional PoFear trains party when zoning out from PoTime!). Then there were moments of fun with other people, moment of awe when discovering new zones or new foes (the first time I saw Trakanon, peeling the pulls of another monk from the ledge leading to Trak's area!), the tingly feeling or maybe discovering something no one else before you did (something that was very possible in EQ thanks to the volume of broken quests that drove most players away from questing altogether) and then achievements like completing quests, finding neat pulling tricks, having epiphanies about the game mechanics, elaborating strats to kill bosses (or more like being the witness of such elaborations by Itzlegend and Iamthep) and of course killing bosses (all the better if it was a server first or a world first - when there started to be a lot of buzz about WoW, because its numbers brought a far broader audience than other MMOs, it was fun to realize that I was not even part of the top 1%, but the top 0.01%!)
A lot of EQ in there, but being in WoW's beta and discovering the polish of this world as well as some of the early encounters (Majordomo! I love that fight - the warping to the pit creates punctual chaos that insures that the fight always remain in the 0.1%) are also up there before it became a mix between magic the gathering (which was a fatal blow to most EQ raiders in WoW I would guess) and Simon Says. I am almost certain I will never play another MMORPG again though.
Also, dev Frizznik raiding Uqua with us as he was probably asked to fix the zone:
