Ok so as our groups DM I was reading through all the monsters and bad guys in the Bestiary and suddenly it hit me. "How the heck are the surface races surviving at all in this world?"
If you take out the 5 evil or commoner humans in the bestiary there are only 4 creatures that DON'T have darkvision or blindsight/tremorsense! That's almost 90% of the things PCs have to fight against!
On the flip side the wonderful folk of the surface world or near surface (for you Dwarves).
> 0% have darkvison
> 50% have no vision aid at all!
Seems to me that one long dark winter is all it would take for the whole surface world to be whipped out. Heck even the drawbacks are unbalanced.
So a Drow comes to the surface to loot, pillage, get a tee shirt, etc...
At night Humans are straight out blind (without a light source) and he has a +5 to AC (total concealment) Drow has no negative effects.
Dawn comes up and bummer now the Drow has disadvantage on attacks (and that’s it)
Now don't get me wrong I don't want to start a super vision arms race here. I am asking WoTC to back it down the other way.
> Have creatures that live way underground like Drow and Mind Flayers have darkvision sure but give them a heavy price to pay if they get in sunlight.
> Near surface critters Goblins, Orcs, etc could have a smattering of low light vision but again don't go crazy.
> Undead and oozes and such should have some heightened sense maybe limited range blindsight etc...
> Surface folk and critters for the most part shouldn't have any vision aid
