Elves never could camp bridge like warlocks and shamans coz rangers trap doesnt stack,multiple traps only work on 1 target while quake and circle can stun all the elves that passes thru the bridge. anyways the bridge change was beneficial for both side.
IIRC, at its first release, blessing could stack. so like rangers can hit a blessing after a blessing(normal hit-> blessing-> another blessing-> another blessing->powerful shot etc) coz i remember seeing a ranger hitting a rabbit 7 hits in 1 second. anyhow if this is incorrect forgive me, my memories of the time is faint.
