I've been about for quite some time, unfortunately my playing times diminished over the years, and I seem to only be able to log on during 'downtime' periods mostly. That being said, from back in the days, what I enjoyed most was:

- Random interactions 'out of the blue' (but you seem to be doing that, so cool, I've had 2000-gold-interactions and 150-hour-stacked-plague interactions, and both were equally cool), both from Imms, and from imm controlled mobs.
- Shorter, one-two hour quests around Thera (around a theme, like there have been in the past for instance a myrdrraal/trolloc attack on Galadon, or that pirate quest that involved the kidnapping of a PC and with several hellhounds involved - this theme can be good/evil; cabal related, just some random event involving all; it can be focused on fighting, running around and solving a small puzzle; quests doable by all no matter what rank, or a group of lvl51s was needed). There's probably tons of ideas in that area. You could have Darsylon swarmed by a skeleton attack, the High Lord sending out his ambassadors to the surround lands to conquer, goblins in Silverwood forest going berserk, a feanwyn green dragon attack on Galadon, a scarab revenant war on all cabals, a quest with several hidden objects around the world, some speed contest where you have to gather a certain amount of automatically-given-things-upon-entering-a-room like a bowl of gruel from Akan Castle, gathering a specific set of clothes for the beggars in Voralia (an evil set, a neutral set and a good set), etc. (Nothing all too new here, but they are still always cool to participate in). You could have shorter imm-run quests to introduce more players to certain less known automated quests, (like some of the more 'hidden' quests in Hamsah - by participating in a quest like that I learned about the Azuremain quest, for instance), shrine locations, history of an area, etc etc. I liked quests that introduced new areas.
- Longer, one-week, two-week quests; some of those that happenend in the past took too long though; and people lose their drive and interest in it (I remember the quest involving all the 'special' dragon items had to be gathered, and the guy just literally always logged in, prayed, and logged off after some time because he didn't want to risk losing the items in a crash when he dropped them somewhere, but on the other hand he was also constantly progged by what-ever, because he had all of them in his inventory). I agree with the tailed star event taking too long. The cadence of the whole story is too .. irregular? One of the very fine examples here was when I played Gorach, and there was some evil being that impersonated an Ice dragon that wanted to create a good-people-turned-evil army; it took about 2-3 weeks, and involved pretty much all good-aligned PC's of that time. (I believe the end of the story was the introducion of the Warlock Cabal?)
