Maybe I'm missing something
Yeah, plenty.
1. They fixed trading by adding "Groups" that you can trade with
2. Seeing few trades gives an incentive to expand. A meaningful choice between having all "easy" map fights and pushing out to new trades and having "medium" fights.
3. Only very very new players in the tutorial chapters would appreciate a deluge of trades offering a paltry 100 goods, everyone else would just see a flood of annoyingly small trades.
4. If your neighbor posted 100 tiny trades it's much more likely that one or more of the many big players near them would clean them up before you did.
5. This one is really important, so read carefully, think about it, and read it again: If a player has a trade up the understanding is that they need the goods,
not that they are "helping out", so if a big player comes across a bunch of tiny trades they will not "leave them for little guys".
This is why your idea won't work:when your neighbor posts 100 tiny trades they will be visible without penalty to
0-2 other small players who may or may not be able to take one or two trades
5-10 medium players who could take some or all
5-10 large players who can easily take all and will because they think they are helping.
That leaves you, the other small player without any trades because all those other players will gobble them up back where we started after wasting everyone's time.
This isn't a theory, it's a fact and we have seen it in many events. There will be a quest to "gain 100 marble" so a medium+ player will post 20 trades to help fellows(and neighbors) out. Sounds good, except another player sees those trades, but doesn't know that those trades are designated for a special purpose and gobbles em up to "help out."
Same goes for the FA all the time. One badge requires "gain an MM spell & gain 100 planks" but if you post 60x100 planks they all disappear very fast, and that's despite the fact that everyone knows an FA is going on.
Still relevant to the game if it's in the game.
You keep mentioning it as if it was recent. If the devs increased it yesterday, then it is a clearer indication of their vision on how things should go. If it was changed from 35 to 60 years ago, there could be any number of reasons why it was done that no longer apply. BTW where did you even find that? I don't recall a 35 limit. I believe if it was 35 that was before FS, right?
