Various feedback

I'm enjoying PoE2 but these are the few things that annoy me/things that I dislike:

Specialized stash tabs
Please turn all specialized 40 points stash tabs into a generic specialized premium tab that can switch the same way you can switch map tab between different series in PoE1 when it's empty. This is much more future proof solution - it allows removing mechanics which have the tab or adding new mechanics to it without it feeling bad for players and it also allows having different tabs for PoE1 and PoE2. Tabs that can be combined are divination card, delirium, blight, flask, gem, delve, ultimatum (metamorph), fragment, as far as I remember all of them have the same point cost. If someone wants all of these tabs they will still need to purchase exactly the same amount of specialized tabs but it will become much more flexible.
Also please turn flask stash tab into flask and charm stash tab in PoE2. Charms took place of flasks and there is also no need to hoard quality flasks for recipe, so why not allow charms, that will at least make tab somewhat useful.

Difficulty spikes
Overall difficulty in PoE2 is great but there are a few outliers that feel overtuned. Some that I felt were overtuned - Trial of Chaos as a whole (modifiers are way too dangerous, collecting soul cores task seems to be almost impossible compared to alternative of escorting), vaal mercenaries with crossbows (their damage is way too high for how fast they shoot, especially considering on maps where they appear they tend to hold chokepoints and can instantly kill you when trying to go through it), poison spitting snakes (would be fine if chaos resistances were more accessible, but as is they deal way too much damage), vaal enemies that spawn spider mines (mines are very hard to see on some builds, needs a more obvious effect when they are preparing to explode).

Chronomancer
I started as chronomancer because I thought the concept was cool, I expected it to be bad because while it sounded cool it didn't have much synergy. But it turned out much worse than I thought. It's basically playing unascended - the only useful parts that I found are the 2 pointers in the middle. Time stop cooldown is way too long (I didn't expect PoE to have a 1 minute cooldown ability), duration is too short (I can freeze bosses for longer without any investment into freeze even - duration isn't even enough to cast comet) AND it has line of sight (the one time I thought it's going to be useful when I saw a very dangerous pack in other room and wanted to use time stop to enter it safely and then freeze them normally I found out that time stop just didn't affect them because of line of sight). Time warp is just bad because after images are created automatically and there is no control where I would return if I use it, please just make first use place an image and then second use to return which would place it on cooldown. And the right branch isn't much better. The only good part are 2 nodes in the middle which give some cast speed and mini temporal chains aura but they aren't worth ascendancy.

Blink
I understand why movement skills need a significant cost after seeing what they did with PoE1 but the opportunity cost of blink is way too high. 60 spirit and a cooldown is already quite a steep price, but understandable, having it remove dodge roll is way too much.

Drops
Exalts are very common in A1 but seem to almost stop dropping the moment it's finished, I got almost as much exalts in A1 normal as I did through the rest of the campaign on normal and cruel. This makes using them for crafting the intended way while leveling pretty hard. Skill gems drop WAY TOO much. Do they even need to be itemized if they are dropping so much that by the time I get skill gems of next level I can get leveled skills of every class? Also while I see a benefit of having lower level bases drop at higher level areas, I don't see a single reason why low level mana/life flasks also can drop in higher level areas. They are a 100% wasted drop.

Sockets
Allow us to destroy runes inside not corrupted items for a small cost. Even D2 had a recipe to destroy socketable. Or even just destroying sockets entirely would be fine.
