true, not always availableNot just terrain.
For that to happen they need:
A) Terrain.
if we are not talking about cr1/4 mooks, everyone has best weapon available(non magic ofc)B) The correct weapons.
just take CR 1/2 scout; two attacks with +4 at 150ft
even with 12 dex, longbow with advantage is a very good choice. you deal some damage and receive none.C) Not to be terrible with them.
dumb melee monsters are just filler or tanks for more intelligent ones.The vast majority of monsters just don't even have a ranged attack. Let alone one worth using and with 150' range. The chances of all that lining up in D&D are pretty damn low in most games.
