One thing that concerns me about the way FATEs are set up.

Unless there's something I missed in that vid, or that is covered elsewhere, it seems that people who are higher level can seriously ruin the experience for others if they want.

They mention in the video that if you're too high level for the FATE and you participate, you don't get credit; that you have to level sync down if you want to get credit.

However, nothing stops you from going in and killing stuff anyway.

So, what's to stop someone who's just looking to troll others in-game from running in on their higher level class/job and one-shotting everything, purely to prevent others from being able to get a very good reward, if any?

I'd like to think I'm just being cynical, but having played MMOs as long as I have and seeing how some people - even in FFXI - will abuse game systems any way they can purely to annoy other players, I have no doubt people will do something like that, if given the opportunity.

Is there anything anyone knows of that would prevent such a thing from happening?
