There are some facts I want to tell you:
1) Accuracy fact: when me and my friend an want to shoot our bows are connecting each other with some wireless technology (WiFi probably) and transferring data about enemies pisitions and weather conditions. If more Archers are closer we have 3d hologram in our little screens fixed to bows and our arrows are flying in places determinated by a sattelite.
2) Dmg fact: When we are connected and arrows are flying in aerodynamical tunnels witch helps them to rotate faster and gets hier energy (Arrows Mental Energy - AME)
3) Killing fact: Thanks of AME (showed to a pleyer as % additional dmg bonus) and 3d holograms Archers can kill an enemy with a few shots
4) Great tactic fact: By devs, best archer tactic is standing close to each other. It will help you and your friends to get bumped and killed by cav. The worst tactic is spreading out and shoot from many directions to an enemy. Destroying shieldwall by constatly shooting at it is better option, most stupid is trying to flank it and shoot from a side
