The freaking inventory, is an exact copy of the d2 inventory.What 12 year old mechanics does PoE use lol
If I want to equip any item I need to left click it, go to the slot it should be and then left click again.
Right click doesn't work, double click doesn't work; we are in 2013 and none of those two options works, hell there are games that auto equip new item drops if they are better than the current ones.
Instead they choose to use the most primitive way of inventory.
That's one example of the developers trying hard to make the game with a nostalgia feeling.
