It is all about reading between the lines.

What they are really saying is that they hate the game and don't want to play it, they only want items so they can quit or brag.

People who enjoy the game do not put such messages in their party comments. Because these value the challenge in beating game content with strangers, even if it takes deaths. The more deaths the harder it is, the harder it is the greater the accomplishment. Who cares if someone beats Twintania with 0 deaths? It is those who beat it with 50 deaths that are the good players who took on the challenge and prevailed.
