We all love this game that are still here. It has been an enjoyable experience for the 10% of us that still play that bought the game at launch. All great mmo’s have raid content. Raid groups are a great idea. Even if were just running elite zones. You have whole guilds running together to clear the elite zones on a daily basis. Why not let them join a raid group?
Raid Dungeons! With the combat system that you have in the game it absolutly makes sense to have raid bosses where it takes 25 people to take down a enemy with really hard wipe mechanics. Keep this in mind. Alot of your player base came from World of Warcraft.
As a company leader. I feel like I can speak for some new world players and say that you would see a influx of returing players if you developed a 25 man raid dungeon. The current dungeons are really easy and its only a 5 man group.
All the people that have quit playing the game have quit becuase they complain that they dont see really good end game conent. Make a insanely hard raid dungeon that takes 25 people at 625 Gear score to complete with insane bis items to get and I bet you people will start playing this game again.
