The effort vs. reward curve is broken. It is reasonably easy to complete the three maps and acquire the three chests. The effort required for further reward, be it prizes or prestige, is Herculean. Doubling or tripling the minimum effort required to get those chests might advance a fellowship from 160th place to 105th. If you're dedicated, you might break into the ranks which grant paltry prizes. If you have a fellowship that is not die hard but you'd like to see how far you can get, you quickly learn that there is no point to doing more than the minimum. There is no mid-range inducement to try and try again, improving a bit more with each adventure, as there is no middle ground between acquiring the three chests and placing in the top rankings.
That's just a defeatist attitude though. Of course teams won't do well if that's their mindset. They've all already quit before the contest began! The effort to reward ratio is a non-factor because it's been stated over and over again that top FA teams are NOT doing it for the prizes.
The top team on my EN server hit ~150k last FA. The highest my group has hit is ~80k+. Well 80k will easily win on some servers, but where we call home, it's a long ways from 1st. We almost need to
double our efforts to catch up to the leaders. We can call it an insurmountable gap and quit, but we don't because it's not about what other groups are doing. Our mid-term goal is to hit 100k because we all know, you can't hit 150k without first hitting 100k. Where we land in the rankings if/when we hit 100k doesn't matter because we've hit our internal goal of improving another 20k. And it's a mid-term and not short-term goal because we take breaks and players come and go like any other fellowship. We have to reset and see where we are with a new lineup. Sometimes we fall backwards before moving forward again bc we lose some key players, but so long as we continue to inch forward, we will always have a shot AND something to play for.
My EN group started from scratch with only 13 players, and less than 5 were above chapter 5. We've crawled our way from 30k to 80k in 2 years. Like, who knows...it might take us another 2 years to crawl to 100k, but it's not like our fellowship is going anywhere. Like, are people disbanding after the next FA that you need to do well on the last hurrah? Elvenar is a slowwwwwwwww game moving at a snail's pace. Sometimes it takes me 4 weeks to unlock 1 darn tech. I think of it as we have an infinite number of FAs to improve with because FAs aren't going anywhere either. Our odds of winning are currently abysmal, but you can't win the lotto until you get off the couch and buy a lotto ticket at the store. And who knows, that top FS might disband too ;D Time works for us in FAs because we started as a tiny group so it means our cities are getting bigger and will have more real estate to play with.
You can't jump from 105th to Top 5 in one FA, but you might be able to jump to 60th. Then 30th. It's actually pretty easy to jump in large hops from 100th to 50th and 50th to 30th. The field narrows from Top 20, then Top 10, Top 5, and Top 3. Those are kinda where the jumps in separating wheat from chaff happens. In our case, we have to improve by 50k to only hop one or two spots, but that's how our competitive field shapes up at the very top. Us chasing down 50k is no different than a group in 105th place working to add 50k to their score. And if someone in 105th work their way to improving another 50k points, then all the other FS on that server will think they're a "Top FA" group too. And the best part is if you can do 80k, then when your group take it easy, you can easily handle 40k without sweat. That's still Top 15 finish without burning out your players.
