FATE is no fun at all, especially if you build content upon it.

In terms of seasonal events I honestly prefer just having solo quest chains that are totally divorced from FATEs like Little Ladies Day or the Easter Event (Thus far) compared to the Swimwear/Christmas events. Were those still pretty minimal? Yes, but at least they had some storyline associated with them beyond the initial exposition you get offered in most of the FATE based ones.

It's a shame because I don't think FATEs would be that bad if they scaled well. As it stands, you either have them too weak for the zerg that's doing them, or too strong for someone to solo (e.g some of the crystal tower fates that no one does any more).
