missneaki, the right fellowship can make all the difference, but most people stumble into a fellowship that isn't a good fit, and then feel funny about leaving. It's a shame. You will find a world of difference if you play with the right fellowship.
When you're in game, click on your ranking points and then click on the "fellowship" tab. Don't go to page one and start looking for a top fellowship, but don't go to the bottom either. Check out the fellowships somewhere in the upper middle, in rank. Check out their "overviews." If they have a good-sounding overview and you think you might like them, write their name down. Get the names of at least 5-10 fellowships that you might enjoy based on their overviews.
Once you have that list, go to elvenstats.com. Click on "fellowships" and then type their names in one at a time. (Make sure you are picking the right fellowship in the right world ... some fellowships have the same name but are in different worlds.) Check out each fellowship on your list for the following:
1. Boosts. Do they need your boosts, or do they have a lot of the boosted goods you produce? If you make silk, planks and dust and they have tons of those but are low in other things, you won't be a good fit.
2. Tourney score: If you're active and willing to contribute to the tourney, then you'll probably want a fellowship that gets 10 chests (or very close, to where you can put them over the top.) A fellowship that gets 3 or 4 chests will not provide you with as many goods as you deserve.
3. Are there a lot of black triangles next to players' names? Black triangles signal inactivity. You won't have many players to play with if there are more than one or two players with black triangles.
4. Scroll ALL the way down to the bottom and look at who has recently joined and who has recently left. If there's been a mass exodus lately, you may not be happy with a fellowship that has just survived a shakeup. Likewise, if a bunch of new players have just joined, you may not have the stability you seek. A nice, stable fellowship, with just a couple joining and leaving on an ongoing basis, is the best kind of fellowship. (Note that this is not always true ... sometimes great fellowships have coincidental departures ... but it's true often enough that I would go for a stable fellowship.)
With that info under your belt, you can select a new fellowship wisely. Good luck!
