Lots of people are still being archers or ranged for they're devious and sinister reasons... why not we remove crosshairs
Because archers suck as it is.
Historically a longbow man could keep three arrows going until he ran out. One striking the target, one in transit, one leaving the bow.
Nations that used short recurve bows such as the Mongols had a high fire rate. At the moment an archer isn't much quicker than a crossbow and with lag affecting things actually hitting a target, let alone killing it is difficult enough.
Taking the crosshairs away would make it nigh on impossible to use the class as was intended.
Let put it this way. We could not re-enact the battle of Agincourt as it is because the archers would only be able to get off one arrow before the cav hit and mowed them down. Why make it worse.
