This one is a bit complicated. But someone have to try, right?

The trading community.

Explanation and why it's happening

As seen by the only few legit playing people. They box players either old or new just to force them into trading. And they keep doing it since the dawn of STW.

This happens because people think trading is part of the game, which in reality it's not and never will be. This is why in every guide posted anywhere mentions one thing: Don't Trade!

If left unsolved

It caused worse problems I will be explaining in this post. Examples would be payment for carries, griefing the mission if not agreed with a trader, Trap spammers, websites that profit money off something that is for free.

Current solutions

Playing in private or with friends and/or premades is currently the only solution.

Offered solutions and the consequences

1-Removal of dropping functionality.

CONSEQUENCES: No player will be able to test a weapon from a friend. People won't be able to move stuff from their mule accounts. Players won't be able to share stuff with new players.

EXCEPTION: Ventures on the other hand has proven this actually working. But people are still against the idea.

2-limiting the dropping of items to materials only

CONSEQUENCES: Same as above with the exception of sharing materials to new players, but it will be a worse solution as it won't solve it.

An actual solution

No solution has been suggested.

The Carries.

Explanation and why it's happening

Basically people being taken into missions while being significantly below the minimum requirement of that mission. Like people below power level 122 being carried into mythic storm king. It's a double edged sword as well because not all carries are bad.

This is happening because people want rewards without putting any effort into it. Playing the game by not playing the game.

If left unsolved

That has caused twine peaks missions to be riddled with people with no idea how to play the game. People forcing "the door" build into every game they play (forced jailbuild history repeating itself). Or the previous community issue I mentioned has reached twine peaks's door steps.

The irony here is people say it doesn't affect people directly, yet the consequences are already happening and it does affect people who are looking for "coop".

Current solutions

Again, playing in private matches is currently the only solution and playing with friends/premades as well.

Offered solutions and the consequences

1-limit the storm shield progress to story quests

This was a not-bad solution, as it forced people to actually play the game.

CONSEQUENCES: People didn't like playing the story quests. Causing epic to remove this requirement back in chapter 1 season 6.

An actual solution

A real solution would be enforcing power level requirements in private matches. This will force people to actually work on their power level.

Yeah, try to say "leveling up is hard!" when I can show you someone who made it to power level 100 in only 20 days. Not to mention it's easy to get everything if you put the effort into it.

People's reliance on exploits to play the game.

Explanation and why it's happening

We all know STW is riddled with bugs, right? Some of these bugs are basically exploits to people to use.

Why this is happening? People, again, don't want to learn the mechanics of this game and rely on exploits to win.

If left unchecked

To make matters worse, people are now forcing these gameplays upon the others no matter how much a person has built. Currently the door walls, and previously jailbuilds (Epic never considered jailbuilds a way to play the game, given on how they keep fixing it)

Current solutions

Private matches, Duh.

Offered solutions and consequences

No solution has been suggested.

An actual solution

No solution has been suggested. Besides begging for epic to fix such exploits.

Griefers And Score Hoggers

Explanation and why it's happening

Basically people ruin other's day, need to say more? This includes people who afk in the mission and/or farming in the game without caring about doing the objective. The score hoggers are basically the trap spammers that put them all over the objective AND on the spawns.

The reasons are people don't want to trade with them, so they proceed to sabotage the mission over something like that. Or people forcing the door walls into the mission, and you get the idea. Otherwise, just another kids looking to boost their worthless ego.

If left unchecked

People no longer able to get mission alert rewards at this case. And some trap combinations can cause critical FPS drops to old gen consoles and low-mid end PCs.

Current solutions

Private.

Offered solutions and consequences

Epic did try to add a solution to the afk, but it failed anyway.

An actual solution

No solution has been suggested. Probably near impossible to fix without epic actually moving their asses and start a ban wave than taking care of their precious arena servers.

All these community issues has one thing in common:

You are forced to play in private matches regardless of the problems. In a COOP game.

We are supposed to play together and help together. Not turn it into a pokemon v2.0 and/or an anarchy simulator. While it's great to not worry about community issues. So in other words, public matches is nothing but a cesspool of rubbish piled together in a radioactive waste.

Playing solo has it's own issues as well:

Imbalanced husks scaling to solo missions.

From stonewood to low end twine peaks doesn't seem much of a problem. But if you try mid-endgame twine, then you'll notice you'll spend more resources trapping objectives. Because you are playing all by yourself. Then you proceed taking your time farming these resources back. Then again you'll spend more resources, in an endless repetitive loop. This is mostly noticeable in ventures. If a person is soloing with no idea how to properly play. It becomes a true frustration to the player.

The seekers of challenges must know there are players who are not interested in looking for challenges as well.

The friends you have, are not always available

Mostly common in any online game. Not all the friends you have will be always available. Some people have life, some people are working, some people are not interested in playing the game. Etc.
