TDE was pretty evil towards the other upper-tier guilds in those days. It was a toss-up between Cobra and them for my least liked people, although at least TDE had the courtesy to speak to you in english. I raided on and off during those days, mostly with the lower-end guilds doing clean-up content and keying up. My fondest memory of EQ had to be helping get Lunacy Unbound up and running (I joined on the third day of the guild) and running people up through Luclin into early PoP content (Valor B and whatnot) while FS/Dili were working on Ele's.
I was briefly in TDE, then left because Euro vs US raiding schedule was killing me. I know that in Velious they dominated, so in Luclin, but from PoP onwards I didn't even follow what they were doing as all my friends in that guild stopped playing.
I ended up in several guilds, all dying one after the other for some sort of drama, which never included me fortunately, at least not as a major character in the plot, until I was in Reunion, a guild formed after the brief life of Wipeout came to an end. To these days I'm still amazed at how seriously and personally some people took "attacks" at their EQ life. I never gave a fuck, played 4 evenings per week tops, had a ton of fun and made a couple long lasting friends in that game.
Collectively speaking WoW holds a lot more memories than EQ, which is normal as I played it much longer, but EQ had the advantage of the first "omg omg it's D&D in 3D" and the fact that it took so long to do anything that you had to make friends and you were meeting people in your same situation, so helping each other was natural.
reunion was a small guild made of skilled people, we do it with less was a sort of motto. I remember when we did Emperor Ssraeshza (but we're only testing the CC part the leader said...) and it was dead in 41 minutes of epic battling, we were few, strong, determined and crazy and thankfully we had necros with essence emeralds. When I did some math and stated that "yes we can kill Bertoxx with 39 characters (31 actual players) and so he died that same night.
I also remember fondly our first (and last) fight vs Rallos Zek the Warlord: we did Tallon and Vallon flawlessly, start the event in the pit, Rallos is at 35% and everything is going so smoothly that I expected a server crash. At one point the tank is pushed *in* the wall and goes out of range from CH chains, but remedy could still land (double range) without healers going under the AE rampage, so while we try to capitalize on Remedy chains, we try tank swapping (Rallos doesn't want to change target), we try Call of the Hero (didn't work) and at the end with RZtW at 25%, we run out of mana and we wipe. We logoff, the following week half the guild calls it and say they quit. Most of us spend a week or two thinking, then we move on to better things as well.
Best guild I was in, ever.
