My suggestion for improvements to the end of the game.

Endgame Improvements

Azmeri Spirits

This mechanic isn't funny because it has design problems with the game's builds. If your build is too fast, you clear the screen before the spirits can do anything. If you're too slow, you can't keep up with them.

My suggestion:

Change the spirit to work as follows: when you approach it, the spirit completes its programmed path without the player needing to stay close, and much faster than the player. Leaving a trail for the player to follow and find the Rare Monster. This way, regardless of the build type, you can kill the monsters without worrying about killing them too quickly or continuing your slow progression if you can't kill them fast enough. Structurally, the mechanic would remain similar but wouldn't impact the build type you're playing.

Towers
Currently, the towers have lost their purpose after the tablet changes. However, the purpose of serving as beacons of which path to follow on the atlas is still valid. I play SSF and depending on the league it's very difficult to find the Arbiter of Ashe because sometimes you just can't find him.

My suggestion:

Reduce the number of towers and place them on top of mountains, greatly increasing their viewing range so that whenever you complete one, a large area of ​​the map is displayed for you to plan your path, and always on the edges of the view of a completed tower there are at least 4 other towers visible at opposite extremes (North, South, East, West). So that the player can open the path to the next direction they wish to follow, but need to traverse all the maps along the way.

Mini Currency Inventory
Currency Inventory
Currently in PoE 2, due to mechanics like Essences and Strongboxes, Omens, it's always necessary to carry some currency, but this occupies your inventory and sometimes you accidentally put these items in the chest.

Having a mini inventory on your Belt, such as 5 exclusive slots for currency, would allow you to carry these items without worrying about accidentally putting them in the chest or losing them in the confusion of the player's inventory.

Rogue Exiles
I have difficulty finding them among the monsters on the map; you usually hear them before you can see them. My suggestion is to visually add something that differentiates them from other monsters, such as an aura similar to the auras above the players' feet in the skins, or add footprint skins to them so they are easier to identify in the crowd of monsters.

StrongBoxes
Similarly to rogue exiles with weak or melee builds, sometimes there's a hidden monster missing, and you don't know where it is. And you waste time trying to find that monster.

My suggestion:

Add a visual mechanic like a fog umbilical cord that links the monsters to the Strongbox. This makes it easier to identify which monsters came from the Strongbox.
