I really think that boss battle against the ancient karka could have been a lot of fun if was not that laggy. Also the reward(I was lucky to be able to open that chest) was nice.
Now that island map is not that big and we have people who want more content for bigger groups instead of only the dungeons for 5 people.
I suggest making an npc that lets us repeast such events. Place it in one of the major cities but not Lion’s Arch or Hoelbraek. Hoelbraek already got the keg brawl npc. Lion’s Arch already is major meeting point of all the player for most other stuff and got the new dungeon. I remember people wanting something unique for the other cities.
Maybe Rata Sum or The Grove? An asuran researcher or some ‘dream guy’ that lets you replay a dream version of that event.
Groups maybe like 20 people and tune down a bit the amount of mobs and of course the rewards – can’t give 20 slot bags all the time lol – to balance it for that amount of players. Hopefully this will be possible without lag.
