Thanks for the article Wint, it is refreshing to see the changes and opinions so far. While I am a happy little legacy member... life hasn't been nice enough to allow for any first-hand knowledge of my own :(
I am curious as to how long a normal FATE lasts for, and how many people you usually see participating? I know that with the saturation in the BETA, that it is an unlikely scenario, but what would happen if you got sucked into a level appropriate FATE and you were the only one nearby. Are most of these hard enough that being the only participant would mean disaster?
Everyone brace yourselves for my next statement:
Kachi was right about FATEs (kind of).
Some of the FATEs have been REALLY busy, especially the ones that occur near Santuaries/Towns. Those are very difficult to participate in at times because of the sheer number of people. I know feedback has been given about that.
Some of the more obscure or out of the way FATEs are totally solo-able, because you can target mobs one at a time and if you're not in a party they don't link.
Some FATEs are not solo-able at all, and would be death to try. One that comes to mind is this one where you have to kill a NM Miqo'te. Since he's the only target, you can't really solo him since he's designed to be brought down by a large group.
Where Kachi was wrong is an LS camping a specific FATE. It's just not possible, everyone has an equal shot at participation, and there's no way to block them from participating. Even the super busy ones I still managed to earn a great deal of XP and company notes from them on my CON, even though I could only cast a spell here and there and probably did a fraction of the damage that some of the other jobs with quicker abilities was doing.
Another note about CON and FATEs, the issue came up where curing wasn't getting you FATE credit, and they are going to be fixing that.
