I'm pretty happy that for once night vision has an impact on the gameplay!
It should give drow a disadvantage in sunlight though (Sunlight sensitivity). To make it fair I think there should be a trade off for all races, due to how many dark areas there are in this game, but that of course also depends on the rest of the game.
On a side-note, this (dis-)advantage would be even more noticeable with a day-night cycle.
Don't sleep on the light spell. It makes your weapon glow with a 14 foot radius.
^^^^^^^^ Don't underestimate conjured light ^^^^^^^^
