I loved Eq1 dungeons and I have fond memories of them. So what did I love and how has it changed? Looking at it from a low level experience in LOIO I remember nervously heading to the Sarnak fort for the first time and making my way/getting help to wherever my group was going to be camping. Because of the mob str, down time, and respawn, we were pretty much allowed to sit at this camp and get plenty of kills + build community relationships/friendships, which are increasingly hard to form in modern mmos because of their fast food nature. I remember the fun of watching my wife lock down a bunch of mobs as an enchanter and saving us from certain death when we did not time our pulls and respawns correctly. Often there were not enough kills at our camp spot. So the grps tank and maybe the off tank would need to memorize the surrounding area (maze like in the sarnak basement area) and pull mobs back one at a time or chaining them. It felt like a challenge.
Fast forward to Eq2 and you have the potential for this set up, but a few things destroy the ability for this. The first things that hamper this are mob leashing, linked mobs that can't be split, and no real crowed control. Its a pain to deal with this while trying to feed mobs to a group and in Eq2 it just made more sense to roam because of it. Add to that the fact that unlike EQ1, Eq2 had many quests that really pushed one to roam instead of staying put and you can see some issues. I personally prefer big open dungeons. I like to see people. I like to worry about the dangers of a train (which is almost gone today). I like needing to really learn a dungeon and interact with it. I like being able to get lost in a dungeon. Sure instanced dungeons are neat and all, but I miss Eq1 and how its unscripted dungeons led to some of my best memories in an MMO. I guess a compromise would be to build dungeons that support how Eq1 did things, but at the same time have epic quests inside of them that might lead to an instanced battle (Eq2). However, do not make it so all the names/loot are only in these instanced areas. Perhaps even make these instanced areas pieces of a long arcing class epic quest that grows with your character perhaps ending in raids at high level. In reality I do not think camping is gone. I think the mechanics that made it fun have been absent in favor of a give it to me now fast food environment.
