AoE Fear made you show up as Linkdead. It was a common misconception that 1/2 the raid went LD when actually it was due to the fear. The raids were very laggy still and that fear lasted forever. The AoE Fear and Damage meant running 90 players at Naggy wasn't insta-win. Player gear sucked back then, nobody could do anything when feared. I always did Naggy where you pulled him to the doorway. Healers would stay down the hallway and heal the feared players as they ran toward them. There were probably waves used too but waves never seemed to go as planned and it was more like everyone just ran at him and did whatever dmg they could.
My fondest EQ moments were during PoP era. Progressing through the Planes was challenging and awesome. Every new zone was an accomplishment. Being in the top guild on the server was fun and added to the thrill but had added pressure of not wanting anyone to pass us up. We were #1 on Xev the entirety of our stay. (Xev opened late-Kunark, majority of guild stopped played around end of Gates of Discord).
After my group was planar geared in PoP, we went back to Kunark/Luclin and did all the old content with 4-6 players. It was soooo satisfying being able to shit-can content with a small group that use to take ~40+ and lots of deaths and time to master originally. I remember keeping Lord Inquisitor Seru on lockdown with 5 players, that fight lasted forever too, like 30-40mins I think. We would 5-man Vex Thal. This content was still relevant for a lot of the younger guilds too, which I did feel bad about sometimes... They had a calendar setup and we kinda fucked it up sometimes with our shenanigans.
It was also a lot of fun discovering & using in-game exploits (no MQ bs). A necro guildie found most of the good shit cause necros were always broken. In Plane of Earth B we could skip everything before Rathe Council, in Vex Thal we could run on the roof and get to any of the bosses (which is how we easily 5-man it). It was all geometry exploits and usually had to do with mounts, basically you could find a crease in the geometry where after enough jumping/crouching/etc you would be able to get through the world. The reason you use a necro is cause there was some clicky for Necro/Sks that insta-cast DMF (dead man floating) and if you spam-click it, while on a mount, while auto-running at a wall, you actually RISE instead of FALL, you pop through the ceiling of the zone-in to PoEB then float over to the Rathe Council area, use summon corpse on your mage and start CoHing the raid. In Vex thal you do the same thing until the necro is standing on the VT roof, summon mage, (or corpses of your group, and necro can simply rez them all).
Also some weird "bugs" later in the game due to Sony's excellent scripting. I remember in the last zone of GoD all the mobs had crazy bad scripting and 1 boss in particular would spawn adds a certain way and the doors would lock and all kinds of bullshit, well this 1 boss we wiped on I was able to FD in a corner, I always had a revive staff on me (would sell & re-buy to recharge them), and I got our raid revived back up... thing was, the door was still locked and the boss stopped spawning adds (and the adds despawned) and once our raid was all back up, we were able to kill the boss without it ever fighting back. Seemed cheap-as-fuck but whatever, this was the kinda shit that was memorable to me
The next expansion with the simon-says zone and epic 2.0s was the end for me. Both GoD and whatever that other xpac was ruined EQ for me. The zones/mobs/lore/everything were so disconnected from the EQ I've known & loved for so long. I also didn't leave for WoW like everyone else... Ended up trying EQ2 but damn, they ruined everything with the lore/world/graphics. Everything was SO restricted unlike EQ where you were free to do so much. I don't advocate exploits but the fact you had levitate and free-roaming throughout the world allowed so much non-exploit freedom.
As a monk I loved exploring EQ. I also remember FD'ing my way to the PoM entrace in NToV before anyone ever cleared NToV. It was hard with all the AoE and shit in that zone. Caster mobs would fuck everything up, and there were tons. Had to get to the entrance, with a mage corpse, too, then make sure you were standing snug against the cubby wall where the PoM entrance was while the mage CoH'd and hope no roamers would come fuck you up. Once we got my group into PoM we all bound ourselves in PoM and lived there for weeks. The exit took you to that Othmir zone (Cobalt sea?) and was actually a nice place to be bound. Was fortunate to be able to bind there as a melee, too.
