Ya the night is unacceptably dark if the moonlight isn't favourable, even with Infravision.
You can manage it by leaving your wilderness XP loop and going to find a place to grind in the city, or use a torch to get to a well lit MOB camp/dungeon until morning. But man, constantly being worried about an approaching nightfall feels similar to counting calories when you're hungry.
Wait until you find out how big some of the traversal zones are. I ran out from the Night Harbour gates by the Necro guild for the first time today and just went exploring. I ran for about 30 minutes straight and made it just 2 zones over. Sungreet Strand and Glass Flats are, if I'm estimating, 8x or more the width of East Commonlands EACH. It was unbelievable - vast with sporadic POIs. Vanguard-esque. I had to stop in the middle of nowhere on a rock for the entirety of the night because sunset came before I got anywhere and I couldn't see MOBs to traverse the zones. There are going to be gameplay sessions where you're a class without Gate, and you ding a critical spell level in a dungeon, but your class trainer is 4 zones West and you have a 2 hour round trip ahead of you.
There is going to be a subset of people that love and defend this gameplay style, but I'm not sure I can do it.
