I still don't understand what you mean. Maybe I'm just being dense.Berk said:
There are many more factors that can be used other then just spells. Terrain, how to move, what to move with. One can use almost every possible thing in their environment, and no by environment I'm not talking trees and such I'm talkin about their surroundings and what is around them.
How is environment any more deadly against archers than against melee opponents? I mean, sure it's easier to take cover from arrows, but that just pins you down and stops you from moving. It doesn't neutralize the archer himself.
