The game bombards you with new item types that you will want to collect, and even after learning how to throw or sell useless items, you end up with an extremely small stash space for manoeuvrer. All fully F2P players know that they cannot keep even items that they will need later, which they either have to put in alt characters made specifically for storage, or sell it and then re-buy it later. Currency has extremely low stack sizes which will force you to constantly upscale it, and you could be forced to downscale it at loss if you need it

While not the worst, the graphics do not really stand out as polished and look somewhat dated. While it does fit within theme of being a grimy universe with many foul creatures, it does not compare to many AAA dungeon crawlers out there such as Diablo III.

While the graphics have received updates over time, a lot of the visuals still lack polish you'd see in most AAA games. Some textures are fairly low res, certain character models look weird when they have armor on, and the animations feel somewhat stiff and clunky. You probably won't notice this during active gameplay, but when you stop for a moment to look around it becomes painfully obvious.

It takes an exceptionally long time to get any wealth, useful items, or access to endgame bosses in this game. You endlessly farm the same maps, hoping you'll get lucky with a few good items, but that usually won't be the case, which can be really discouraging to keep playing. This is made worse by the fact that your character progression comes to a grinding halt near the upper 80s of character levels, requiring you to buy insanely expensive items to feel any progression at all. If you don't like grinding, you'll get quickly bored of Path of Exile.

The game heavily punishes any experimentation for new players. Unless you have near perfect understanding of late game and the various viable build-options you are more or less unable to experiment your way into viable builds (and the options for correcting mistakes are limited at best). So, unless you are fine with having to scrap a bunch of characters for being sub-optimal, you are more or less forced into following player-made guides to learn the game rather than through engaging with the game itself. This may or may not be a problem for you.

There's quite a lot to learn when starting to play Path of Exile. There are the mechanics, the crafting system, and the skill gem system. However, the most intimidating factor is the massive skill tree with over 1000 skill nodes, 6 classes and 19 subclasses, allowing you to create hundreds of unique builds. Unfortunately, creating a functional build is really difficult, taking hours of theorycrafting, so it might be better to stick to guides as you're starting out, unless you're fine with possibly messing up.

The western PC version of Path of Exile currently requires using an external site to find deals or sifting through scam attempts in the trade chat. After you find an item you want to buy, you need to message the seller, and if they respond, enter the same area as them to make a direct trade. There is no auction house, no mail, no automated trading posts, and to sell stuff you have to buy a premium stash tab via a microtransaction.

Online play with melee classes may lead to some "rubberbanding" when latency causes the player's computer to desync from the server.
