For me personally, FATEs feel unbalanced. It's too many people (still, even though billing kicked in) and the mobs are real pushovers. I can see FATEs shine when I find one in a secluded area where I'm (almost) alone. There it is fun and I even feel (slightly) challenged. So, for me FATEs aren't entirely bad per se. But at the moment I'd rather avoid them. They're needlessly frustration and grindy at the moment. I hope SE does something about it.
