I totally agree OP.

FATES simply involve mindless zerging from one to the next with no skill required whatsoever.
I wish they would just remove FATES completely.

I'd even go as far as to say remove Odin and Behemoth in their current format, and make those a "special event" that only happens once in a blue moon where the first 48 level appropriate players to interact with a portal/switch/whatever are pulled into an instance for the fight. Even better, have it where it will select the ideal number of tanks, healers and DD's from those that got there first and auto party them inside the instance, beginning the fight once all parties are filled. And as they are such rare and special events, with limited seats, the rewards should reflect that and be epic if the players beat it.

Just my thoughts.....
