Qarn..

[Absurdity]

For new players it might be a bit of a steeper hurdle but that is because of several factors. The design changes over the years made every job perform a lot better than it did when the dungeons were originally designed. You can argue that they have become a lot more boring at lower levels (something that I would agree with) but their performance in terms of dps output has increased by a lot, this means that in most low level dungeons you rarely even see a boss perform more than 1 or 2 mechanics, even if they have more. So by the time you do not completely stomp them anymore and have to actually deal with mechanics it can easily overwhelm new players because they never had to do so before during their leveling experience.


Another issue is that because of how quickly you level nowadays there is no reason to go out in the overworld and do levequests or fates anymore since there are quicker ways of gaining exp. This does however mean that you'll probably be completely unfamiliar with new enemies in a dungeon and what they can do.

Let's take Final Sting as an example. If you would've leveled the way you did back in ARR, the time those dungeons were designed, you probably would've already encountered wasps before by the time you get into Qarn, be it for a levequest or a fate. Those may not have had Final Sting but they did have some kind of sting ability that you know you can interrupt by stunning them. This isn't the case anymore.


These dungeons are basically relics of the past and of a slightly different design philosophy, maybe they're in need of an overhaul as well.
Jobs have however been significantly simplified which gives you more time to concentrate on what mechanics the enemies do, this is especially the case for jobs below level 50.


And even if you die to them once or twice, what's the harm? I think the "you go in, you fight, you die, you learn, you try again" design is a pretty good one. If people are willing to learn then they might die to Final Sting or Doom once or twice but the 3rd time they know to either nuke or stun the wasps and to get on the platform.
