My feedback from my first day of playing:
Walking closing inventory/crafting screen feels bad
The icons of items in your inventories do not have great readability. When trying to craft, I found it difficult to find wood/metal etc. and when sacrificing spending 3 seconds mousing over everything to see what it was felt frustrating.
Targetting NPCs to initiate dialogue feels precise
Starting out with abilities on my bars but no obvious way to mouseover them was confusing
The loading screens seemed especially slow. The game was small so a fair bit seems streamed, but the loading is noticeably slow
When you change a graphics setting it automatically applies. This made it difficult to change certain settings.
It was not clear when you got items from quests and not clear when you leveled up.
Some of the quests were confusing. I was usually not sure where I was meant to go.
The leash range of some mobs feels short
The map takes a minute to open. This made figuring out where I was hard.
Scrolling to read a talent and having the talent window zoom out felt wrong
Theres not meter for how many arrows you have, and no way to tell how degraded your pick/axe is without opening the inventory
Changing your ability bar feels a little awkward. I would like to be able to drag abilities that are on bars and "swap" abilities.
Some of the keybinds feel awkward: Z and U for weapon switches was weird
It was hard to find active PvP spots: usually felt like nothing was contested
What I liked:
The talent trees were really cool
The combat was fun
It looks great
The races are cool
The classes look fun
