Just to echo some of the feedback and discussions here and to put in our 2cents so that (hopefully) Inno hears us all...
Our entire FS is feeling that the Fellowship Adventures, as they are, are NOT anywhere near worth the time and effort it takes to finish. :-(
We're ranked #13 or #14 in Elcy and we've completed both of the other 2 FA's to give the idea a good try, but it was rough. We've decided not to put any effort into this one (we're not even playing casually) since the Rewards/Prizes are not worth slugging through the exhaustingly poor UI/tools they've given us to work with, the lack of in-game tracking and communication tools, and the low-value rewards.
The consensus is that the UI would have to be easier (create a user-friendly quest organizer, in-game event specific communication tools, and a tool for group badge inventory/planning/tracking, etc.) and it would probably take prizes like Expansions or Diamonds at this point to get us involved. It's a good idea, but it just seems they spent too little effort in the workings of such a large event, throwing us scraps to get engagement ($$$). Bummer Inno.
Here's hoping they hear us and decide to work to make this event actually FUN and REWARDING.
