I disagree with the list presented as being "the game's fault" and not the players'.
Ultimately it is the players that are in control of their social behaviour and interactions. The game and its developers and community team can try to enforce against negative interactions, but there is no way they can stop or control it, that is the responsibility of those involved in it, ie the players.
My thoughts and opinions on the list.
1) The idea of tomes/marks/etc. for gear is not new or unique to this game. It was implemented here and in previous titles because players expressed their dislike for being slaves to rng for loot drops, they wanted to feel like they were making progress towards something by doing the content. The devs for this game game us a mixture of things, where you can acquire the standard "end game" gear through tomes, but there is also the method of gearing by getting drops for gear in the end game raids and trials. They are trying to provide multiple methods of acquiring gear for the players.
2). This is simply a case of players always being able to chew through content faster than it can be developed. This has and always will be the case. What takes a player 30 minutes to play through takes often times months for a team to develop. Also, the dev team is trying to create more varied content that the players can participate in if they don't want to grind dungeons. For example, I play Seal Rock and get tomes from that as well as Wolf Marks and PvP XP when I don't want to run dungeons.
3) I don't see how enforcing a difference in performance based on skill level is a bad thing. If bad players can perform just as well as good players, why would anyone bother to try to be good and perform in the game. Allowing players to get by while being bad/lazy imo hurts the game and the community way more than asking people to step up and actually perform.
4). Not quite sure what you mean by this one. If someone is playing the game, they have the internet and are just as capable as anyone else playing to do research on things. Just like with anything that I may not know or want more information on in to, I research it. If I am going to being trying to tackle new difficult content for the first time, I will research it so I know what I am getting into. If you are speaking to making in-game parsers available, I wouldn't be surprised if something like parsers being built into training dummies happening in the future. Originally the team was against their usage because they didn't want them to be used as a tool to belittle or shame other players in game, although that happens anyway.
5) They do reward players for being nice and helping out. That is what the bonus tomes for playing with a first timer is for, that is part of the intended purpose of the Roulette (so that you will get paired with people wanting or trying to clear certain content), and that is precisely what commendations are for.
6). Finding random players to group together to do content is the entire point of the Duty Finder, to pull from a large group of random players that have registered interest in doing certain content so that they can be paired together more quickly and participate in that content. There are of course other ways of doing the content, such as preforming parties through the Party Finder or by talking to other in your FC or LS's or hell even in shout.
So, I definitely don't feel that it is "the game's fault" and players really just need to be held accountable for and own up to their own actions instead of trying to shift blame, whether it is to other players or the game itself.
