Just make the arrows faster. That is all.
Now that i started playing archer that is the only problem i would love to see go away, because now i have to go very close to the battle to actually hit something and do damage. It's just not cool to see your arrow hitting the ground 20 meters in front of your enemy, even if u aim like 30° (or more) higher.
Any kind of xbow-nerf would be great, too, but i can live with it the way it is now. I just don't shoot at xbows who are aiming at me. If they can't hide i pwn them ofc, but that is like never the case. If they can hide, they usually pwn me...they can just stand still and wait for me to do so as well and then BOOM...dead. Or i'm just a noob =(
And one thing more: Headshots should ALWAYS kill the opponent. At least at a minimum of like 25 cut-dmg and 5pd or so. I've seen many tincans survive headshots and that just sucks. It's hard enough to headshot somebody and when u do, they just survive. for teh lulz.
