After a few days of travel across the plains, you notice a group approaching you from the south. It looks like they have been following you, and are starting to gain ground. You (making a good perception check) note the symbol of the dark triad on their clothing, an evil cult you all have pissed off before. They are about a 1000 feet off, what do you do?
Sharpshooter Archer: I wait till they get within 600 feet, and then I start taking them out!
The cultists also pull out their bows and begin firing at you archer. What do the rest of you do?
Melee Barbarian: I will pull out my bow, but start moving 40 feet a round to get closer.
DM: Alright, looks like the cultists are also moving and shooting to get closer, so should take about ~9 rounds to close to melee.
Melee Barbarian: Well....I have a +2 ranged attack at disadvantage....um here goes.
Wizard: Yeah....I'm not proficient in a longbow so....I'll guess I'll keep moving until I get to 320 feet with my shortbow.
The combat lasts for round after round with the barbarian missing every turn and the wizard just double moving, the archer decimating cultists but also taking a lot of damage in the process. Its....not the most exciting fight.
