Would you like an in-game parser?

[Yeol]

sorry, but anything short of high-difficulty content is not going to provide a lot of self-improvement...

Where exactly in my post did I specify which content I want to be more difficult (Less brain dead)?
I said it in a general term. As in everything needs to be considered, from solo content to group content.

... no one wants to look bad ... That's why they will try to get better once they see they do poorly. It's called a "shock therapy"... it is the quickest and most effective way to get better. The drawback is clear however that people with certain social or mental issues, like social anxiety or depression, may go the other way around.

I understand what you are saying but sadly I rarely see this happening in-game.
I'll give you an example. When someone is failing mechanics a lot or not using some of their skills/abilities and gets called out for it. What do you usually see them do?
They either, defend themselves or rage quit. You'll rarely see someone apologizing and willing to learn. We even have a popular topic about these encounters in the forums.

So letting people know that they are doing something bad isn't always going to make them want to improve. Not with the 'you don't pay my sub' mentality.

By making parse public we will improve in the long run, but we'll go through a very harsh phase where kicking dead weight is allowed. Which is what the dev team don't want. Thus why they are trying to close the gap between good players and bad players first.
