For the first 50 character you have FATE's aren't really necessary. But when you make a second, or third, you are a bit screwed. Low level quests do not reset, and leves are limited. So FATE's, imo, are based more toward those leveling alternate classes. I don't mind getting some of my exp from dungeons but as a DPS you can expect to wait close to an hour for DF to pop. Heck I tried to use DF as a CNJ just yesterday and it still took ages to get in. If FATE's get nerfed, then SE has to either reset low level quests so we have a way to level or increase exp gain in dungeons.
