I've read the back and forth between Utnayan and Popsicledeath. Both of you are making valid points and neither of you are wrong. As a Day 1 player of EQ, there a lot of things about that game that were a lot of fun (to the point I wanted to spend as much of my free time playing EQ as possible) while there were a lot of things about it that were annoying and I did not like which caused me to abandon the game for WoW the day that game was released.
Regardless of whether it was intentional or not, there were some aspects of EQ gameplay that I haven't seen in any MMO since that IMO made EQ more fun.
1. Server drama. I was always a casual player but I always enjoyed going to my server's EZboard forums and reading the drama surrounding guild competition for raid bosses, who ninja looted something valuable from a raid boss, etc.
2. Player reputation. Since EQ was very unfriendly to alt characters, a lot of people focused on playing just their main character which meant there was a good chance of you interacting with the same player over and over. Your reputation as a player mattered since it affected your ability to join groups and guilds.
3. Acquiring loot was memorable. One of my biggest dislike with WoW and all its clones was how loot upgrades dropped like candy from a pi?ata. Every level you got inundated with green, blue and the occasional purple item that provided only a small, incremental increase in your character's power. I much prefer acquiring loot upgrades to be a rare event and when you do get an upgrade, it's significant and noticeable.
If Pantheon is ever released and its design promotes those three things above, I will definitely give it a chance.
