I can see a reason for finding people leveling their characters without taking the care you could consider normal.

We are near an expansion and the goal for many players is reaching level 60 as soon as possible. You gain levels and exp much quicker than before. And you will have new abilities at top level. The gear you get becomes useless very quick since you level so quickly. This is not an excuse to not read the tooltips and a guide, just an explanation of our situation.

In ARR when I leveled the 1-50 dungeons were harder, you gained exp at a slower rate and you would have to run many times the same dungeons. You would be gearing up, doing your class and job quests, etc. There were very very frequent wipes in dungeons from Brayflox Longstop onwards, lots of people were leveling their first class and that was a very central part of the game. 50 was the level cap and learning to play your class at level 50 was the goal.

With Heavensward all the content level 50 and under was made quite easier and quick to do so that people reach Heavensward as soon as possible. The important thing was learning to play your class at level 60, there will be new abilities that change how you play the class and it is not so important to master the level 50 play since you'll have to learn a new one.

With Stormblood near, leveling up quickly is even easier, because the goal is reaching level 60 before the expansion, and gearing up your level 60 job. It is normal you find people that are leveling up and don't have for example at level 55 the gear most players had when Heavensward started and most people were still leveling at that level.

This is not an excuse for not reading the tooltips and not making an effort while playing with other players since it's not your time only you use, but other people's times. But an explanation of why now you meet much more undergeared people who have not learned to play their class in the leveling dungeons as you did before.

I've always found one of the biggest shortcomings of this game is while leveling a class/job you are just given new skills. Nowhere within these quests are you actually taught how to use said skills properly. I personally think it would be great if you got the new skill at the beginning of the quest and then the instance for that quest they make you use the skill so that you actually know how and why you are using it in the first place.

Maybe I'm just a fool, but if a skill like Heavy Thrust says "increased potency from the flank", then I'll try to attack from the flank, even if it's PotD. You know, to memorize it.
DPS certainly have it easier to learn their jobs in PotD. Jobs like Summoner cannot be mastered in PotD, but even so, reading tooltips helps you understanding basic functions. Like playing DoTs on one enemy, using Bane to spread them, etc.
Heck, some straightfoward jobs like Dragoon are so easy to learn that you can figure out their rotations in PotD. Keep in mind that learning does not mean mastering.

As for tanks, even PotD can put you in situations in which you need to use defensive cooldowns - especially if your potions are on cooldown and you got no healer in your party.
Healers, however... they should at least be able to realize that doing DPS is the better alternative to jumping around when there is no need to heal.

I mean, it's not like I am expecting wonders, you know? Or is figuring these things out already beyond the average MMO player?

Smn can't do a proper rotation. .. dot dot dot oh it's dead.. potd is why I'm seeing more and more summoners spamming ruin 1 in aoe packs... that's all they get that's worth using on mobs that die fast. Same reason why drgs aren't using geirskogle. You can't keep botd up if you use the move. I've seen quite a few drgs in expert using botd and keeping it up but not using jumps or gskl.
Any lower potency move is garbage in potd.

The closest thing we get to a skill description is Darkside lol, "Use it too much and you will succumb to it."
