I also thought that the closeness of the community was the main strength for Fiesta. Most people get time to develop friends and learn the names to the guilds/people they see often in their server, and the main forums are well used so people can meet others there too.
Imo, the KQ quests and new abyss ruined a lot of it. KQ has always been about teamwork, but now it's just getting quest kills. Nobody ever focuses on finishing the KQ because the KQ reward is so pale next to the quest reward. A lot of people now stay behind to kill monsters for their quests and detatch themselves from the main group, making the entire KQ fail.
The new abyss, no explanation needed. I don't see the point of making abysses free to all levels, because that's just like a regular map, except perhaps smaller and with PvP. It's bait for any bully out there that just wants kill points or to harass others because they're bored.
One thing I really miss are the good guild wars. Before FBZ, that was the only way to fight someone else and it was really exciting xD I always get pumped up during guild wars because guild chat flows along so fast with random strategies and comments. Now, most of the time people don't gw for fun, they gw to harass or to avenge.
Btw, what do set items mean? LOL.
