A self-improvement tool is needed in this game, especially for end game

[Whanext]

From my knowledge, part of toxicity in the game community is due to the huge skill gap between players. It is never rare to see many people under-performed in High End Duties, and there is no way to tell those people that they are the "weaklings" or not good enough at this content in a helpful and non-rude way. In another word, these under-performed people are carried by other people who know how to play their roles, and this is unfair in any aspect unless in a premade party. According to the rule, third party software is prohibited, so a suggestion through the information from third party software has a risk of being banned, though it is from a good intention. In fact, this does not stop toxic behaviour rather than encourage such behaviour as such "got carried" players always exist without knowing anything.

When I started to play this game, I had no idea that I was under-performed until someone told me so. Before that point, the game has no way to tell me how my performance is in any specific duty. Even though we have stone sky sea, many players still do not know its existence as SSS is never mandatory. Since SSS is not mandatory, players can safely ignore it without getting any troubles.

An in-game official self-improvement tool or performance checker is needed in this game, and this should be required to join parties in party finder. It is not only healthy for this game and also for the community. The reason why so many people are ignorant about their own performance is because they have no way what so ever to get such information or stats through an official way, and this will increase the skill gap even more in the future between the people who knows about their own job and the people who knows nothing about their own job.
