Some things I think might improve Wicked

Gem Cutter - (perhaps via Markos? chemical removal)
Can remove gems from gear at the expense of gear (remove gem safely, destroy gear)
Can remove gems from gear at the expense of gem (remove gem crudely, saving gear)
Able to combine/refine a gem to give its max value (still able to use watcher to exalt the values but this gives an earlier avenue for gemming gear)

Tavern -
Tavern upgrades give emotes per tier
Tier 1 Sit (sit would be ideal for screenshots!)
Tier 2 Cheers!
Tier 3 Dance

Elleanor (Enchanting) -
Able to disenchant gear (revert it back to common)

General Information - (Number/Percentage displays being allowed as an option)
Able to see what runes in gear do while they’re inserted
Damage numbers displayed where applicable
Minimum/Maximum values on gear displayed
Armor values give an estimated damage reduction
Elemental values give an estimated damage reduction
Health/Focus/Experience/Weight numbers overlayed/displayed by appropriate bars
Tool durability displayed via small number on use/inventory screen (perhaps via a slight green background slowly changing to red)
Better explain key words (Fatality, Overall Speed, Regainable Health, Infusion, etc. PoE2 gives you popups explaining these on hover)
Display estimated chance to resist a stagger based on poise
Pestilence bar has a percentage
Give information on the item a blueprint allows you to craft (particularly weapons)

Give armors an inherent effect (Examples: cloth-focus gain, leather-movespeed, mesh-attackspeed, plate-bonuspoise) and display this fact
Place to rewatch the cutscenes (perhaps an option from main menu)
Remove “based on durability” making them values flat percentage increases
Give an option to swap between overworld/underworld map (like Elden Ring)
Give a “claimable” free respec when first speaking to The Watcher under the guise of “you’ve washed up shore and lost a bit of your memories”
Able to backstab while sprinting
Able to HideUI
Widden the parry window slightly (give a bonus to shields/specific weapons-large bonus to small shields, medium bonus to medium shields, none to large)
“Make Offering” hotkey doesn’t seem to work on PC
Reduce fall damage
Loading progress for black screens (perhaps like the circlular bar near your character that displays stamina)
Slightly increase the “walk” threshold for moving mouse nearer to/farther from your character
Buyback/Recent Buyback from vendors

NOTE:
This is after 100 hours and I haven’t done much Crucible
I may think of more in the future but these are a few things I found myself wanting while playing
