Im not sure if anyone (myself included) mentioned it previously ... and im too lazy to check all 5 pages ... so i just say it (potentialy again).
- Option to choose our starting gear in character creation.
(Also, option to wear Githyanki armor for Githyanki character would be most appreciated ... and if im allowed to dream wild for a second, some "typical armor" for every race would be really cool!)
- Option to choose also Boots, Gloves and Headgear ... statless, but visualy fitting to rest of our outfit.
(It pains my heart that every single druid in game have those beautifull leafy gloves ... but mine cannot.

)
- Give "older classes" (especialy Rogue, Ranger and Wizard) actualy their own (read as: class-themed) armor, just like Druid have ... instead just generic stuff wich we loot from first corpse. :-/
Now if something needs a homebrew upgrade, I'd say it's Monk. They are by far the weakest base class in 5e.
Im actualy really interested about Monk implementation ...
Especialy i wonder how Larian plan to weight out the fact, that they will often have no weapon to dip. O_o
