Please implement something to teach players how to play

The problem you're ignoring is that you lack information that will let you know what that other player's best is. Are they disabled in some way? You have no way of knowing that. Are they running the game on a potato PC barely meeting system requirements from a low speed internet hotspot? You have no way of knowing that.

That's not really SE's problem. While I would agree that we need more tools to help disabled players, no need to assume that everyone is disabled. Potato PC is really a player's problem. And it's also what's holding SE's hands tight when it comes to adding more functions or expanding features.

They may very well be trying their best even if it doesn't look that way to you.

What you can do is decide whether or not you want to be in a party with another player who doesn't meet your personal standards. You can try to get the rest of the party to agree to remove the player, or you can leave on your own. I've left parties when there was literally a player who was not trying. I'm talking not even doing a single or 2 button mash, I mean just following the party at a distance usually making stupid comments. The rest of the party wanted to carry that person and wouldn't agree to a kick so I left.

And I don't disagree with you on this one. What's mindboggling here is that some people think that it's fine being lazy. It's simply disrespectful to everyone. And it's not about my personal standards. For some reason it's fine to be lazy and disrespectful, but asking the said player to work with others and stop holding everyone back is not.

But those situations are so extremely rare. Most of the time, everyone in the group is contributing to a reasonable degree. Maybe a dungeon will take 25 minutes instead of 15 minutes? Doesn't bother me as long as everyone's got a good attitude about things.

While it's fine to spend a bit more time than on some duty, if you start having more and more of those runs (and you will because of players influx), this additional time spent in a duty will accumulate into hours and days, you just don't feel it yet. The quality will drop. Even for defenders of lazy players.

Why are we trying to get SE to divert development resources that could be used for improving job depth, creating new dungeons, etc. just to try to force a tiny percentage of problem players to change that have no interest in changing?

It's not tiny. 14 "teaching system" is very outdated. It needs improvement. Right now people are not bothered to learn because everything is so simple. Until you actually get to harder content and get "gated" from it because people there want to actually clear stuff and get rewards.

I mean if those people already have that mentality then there's nothing SE can do about it, no matter what training features they add.

It's fine, let them be then. Just don't let them ride your back when you meet those unless you're fine with that.
Altho, if we had a better teaching system that would interest players to learn, it's only a benefit for everyone. You still won't need to be the best, you will just have more knowledge about things, thus create good habits for yourself.
