There have been several issues with the current hunt system throughout the Shadowbringers expansion. A number of the issues have come from one main major thing, and that is overpopulation. And I'm going to tell you right now that those issues are going to get significantly worse soon.

With FFXIV getting a big surge of new players lately, soon enough they will hit max level and start doing hunts. Individual servers have been getting maxed out, login/transfer queues have been getting longer, the game itself even sold out at one point there, and I imagine they will be adding in new servers soon. On top of this data center visit is coming soon which is for sure going to increase hunt attendance by a significant amount, even if it's just going to be limited to regions only at first. And to top all of that off the new expansion is coming out near the end of the year which in itself will easily increase the hunt population by at least 2-4x, trust me, that is what happened for several months after Shadowbringers launch.

Let me highlight several issues majorly or partly caused by the current overpopulated hunt scene.

The obvious one - PS4 & low spec PCs users not being able to participate or enjoy hunts as much. Sure, you can be one of those people who respond to these people with "LOL just get a better rig", or you can recognize this is a legit issue. A large number of people have completely given up on hunting, which they previously found fun, due to this. On nearly every hunt train you will see at least one person complaining about the train going too fast or the amount of lag. You will see people who constantly miss out on the first mark of each zone, or land in time to only do one or two hits in which doesn't feel good. The same of course goes for S ranks.

Hunts in general are not designed for the current number of people that do them. From enemy abilities constantly not hitting due to AOE ability caps, to the hunts themselves not having a chance to use all of their abilities before they die, to A ranks not rendering in, and to multiple people constantly literally yelling at others at nearly all S ranks, including "current expansion" S ranks, to stop DPSing because it is dying too fast. (which again doesn't feel all that great gameplay-wise having to hold back) Not to mention the actual difficulty level of the hunts is designed around fewer people.

In general, things currently seem more reward-focused rather than fun-focused or "hunt" by definition focused due to overpopulation. (and also technically due to scaling reasons for previous expansion hunts)
