What little, or maybe even big things did you see that were just icing on the cake?
I will start
Press F to loot... WOOT! I dont have to interact to pick stuff up! Finally a big name MMO uses this feature!
This is a bigger thing but the event system over a quest based system.. I don't know how people can say its similar.. I never once felt I was doing a quest. I just explored and killed things as I went, if there was an attack nearby I helped. Usually completing hearts while I was at it.
Water spray.. when you surface from underwater.. so pretty.
Finding rare recipes on karma vendors.. that was fun I was able to make great gear for myself and it was lower lvl mats, this offered me 2 ways to lvl LW at that point.. with the new leather.. or the old. Not to mention the gear itself was way better than what I had waiting and had a lower lvl req.
SUPRISE CHEST! I was out exploring.. decided to kill this veteran Jotun and his minions and found a chest.. didn't get anything nice but finding it was fun. (no not a mystic chest)
Puzzles! I did 3 puzzle challenges, 2 success and 1 failure. The failure was the underwater one a few have featured in their vids that was overtuned last press beta... we lost because we forgot to get the sword before the roof reformed and we were stuck. In order to access that one you need to be at the end of an event chain so we didn;t have to to go back. The 2 I completed were great.. one was a jumping puzzle offering a skill point and the other was a jumping/combat one that ended in a chest.
dye system and dying town clothes. So my husband kept asking me about my town clothes and I finally showed him what I felt was very underwhelming and awkward looking(Norn female) but then I realized I could dye it.. at first I was wondering why I had so little dye options for the parts of the clothes.. then I saw that there were 4 options(not every piece utilized all 4) and I turned my boring set into something I absolutely loved!
An option to take a high graphics settings pic without using high graphics settings.. I found this little gem in the keybinds that lets you take awesome pics no matter what you are playing on however it will freeze you while its rendering so not good for dangerous situations
Now I am sure there are more things I can't think of but that should get it started =D Here is a pic showing an example of the bottom 2. That fun purple is called "grapsicle" and was found from cultivating a dye seed. I think that teal is standard Norn but might be another dye from seeds.
